Plant Growth-Promoting Effect and Complete Genomic Sequence Analysis of the Beneficial Rhizosphere Streptomyces sp. GD-4 Isolated from Leymus secalinus

Plant growth-promoting rhizobacteria (PGPR) are beneficial bacteria residing in the rhizosphere and are capable of enhancing plant growth through various mechanisms. Streptomyces sp. GD-4 is a plant growth-promoting bacterium isolated from the rhizosphere soil of Leymus secalinus. To further elucidate the molecular mechanisms underlying the beneficial effects of the strain on plant growth, we evaluated the growth-promoting effects of Streptomyces sp. GD-4 on forage grasses and conducted comprehensive genome mining and comparative genomic analysis of the strain. Strain GD-4 effectively colonized the rhizosphere of three forages and significantly promoted the growth of both plant roots and leaves. Genome sequence functional annotation of GD-4 revealed lots of genes associated with nitrogen, phosphorus, and sulfur metabolism. Additionally, genes potentially involved in plant growth promotion such as indole-3-acetic acid (IAA) biosynthesis, trehalose production, siderophore production, and phosphate solubilization were annotated. Whole-genome analysis revealed that GD-4 may possess molecular mechanisms involved in soil nutrient cycling in rhizosphere soil and plant growth promotion. The bacteria also possess genes associated with adaptability to abiotic stress conditions, further supporting the ability of Streptomyces sp. GD-4 to colonize nutrient-poor soils. These findings provide a foundation for further research into soil remediation technologies in plateau regions.

Effect of Peanut Intercropping on Arsenic Uptake and Remediation Efficiency of Plants in Arsenic-Contaminated Soil

Phytoremediation is an economically viable and environmentally friendly technique among various arsenic-contaminated soil remediation technologies. Field plot experiments were conducted to investigate the effects of peanut intercropping with sunflower, lucerne, and jute on the growth and development of intercropped crops and the efficiency of arsenic (As) remediation in polluted soil within the intercropping system. The results indicate that intercropping peanuts with other crops can enhance the biomass and yield of the crops. The land equivalent ratios (LER) of the three intercropping patterns were 1.03, 1.70, and 1.17, respectively. The intercropping pattern also influences the absorption and accumulation of As in crops. Total arsenic accumulation in peanuts intercropped with jute reached 493 μg·plant−1, which was significantly higher by 29.5% compared to peanut monoculture. Additionally, the translocation factor (TF) and bioaccumulation factor (BCF) of peanut seeds were significantly higher in peanut-jute intercropping compared to other treatments, but the As content of peanut seeds in all treatments complied with national food safety standards (GB2762-2022, 0.5 mg·kg−1). Intercropping of peanuts altered the pH and Eh values of rhizosphere soil, further influencing the percentage content of various forms of As in the soil, and reducing the mobility and effectiveness of As. The metal removal equivalent ratios (MRER) for the three intercropping patterns were 1.30, 2.11, and 1.26, respectively. The intercropping of peanuts and lucerne resulted in an MRER of 2.11. It indicates that peanut intercropping has a significant promotion and high restoration efficiency on the growth and development of lucerne. Therefore, among the three patterns, the peanut intercropping lucerne pattern has the best effect in applying to contaminated soil, and can better realize the integration of economic and ecological benefits.

Nano-bioremediation, a new approach to degrade veterinary antibiotics from environment

Nano-bioremediation is an interdisciplinary approach that includes nanotechnology and bioremediation. This process has emerged as a potential solution for diminishing the harmful effect of pharmaceuticals from soil. Overuse of these antibiotics in animal husbandry has led to their accumulation in soil, posing risks to environment and humans. This review provides a concise overview about the present scenario of nano-bioremediation research in the context of veterinary drug detected from soil, also the mechanism and efficacy of nanoparticle-based remediation methods compared to traditional methods. The key areas such as metal-based photolysis, catalytic green chemistry and green nanotechnology are also explored in detail, highlighting their specific mechanisms for antibiotic degradation. The review also emphasizes the toxic effects of veterinary antibiotics on soil, plants, animals and humans, underscoring the benefits of nano-bioremediation over conventional methods. Nanoparticles are prepared in a manner so that they can efficiently absorb, degrade, or metabolize the veterinary drugs present in the soil. Bioremediation along with nanotechnology increases the potential of microorganisms to degrade toxic micropollutants into simple byproducts. Using nano-bioremediation technique, it was observed that the concentration of veterinary antibiotics was substantially reduced. The collegial work of nanoparticles and microbial actions significantly increase the complete degradation efficiency, making nano-bioremediation a promising green technology for soil remediation.

Kill two birds with one stone: Biochar immobilised polydopamine coated compound bacterial agent for remediation of dibutyl phthalate contaminated soil.

The severe contamination of the plasticiser dibutyl phthalate (DBP) in agriculture soils is often accompanied by a decrease in nutrient utilisation. Though the combined application of a variety of microorganisms can simultaneously address the problems of soil contamination and nutrient deprivation, the activity and function of microorganisms can be severely inhibited by DBP, and studies on their protection under DBP contamination are almost non-existent. In this study, a compound bacterial agent KPSB was prepared by optimising with Fe3O4-modified biochar loaded with DBP-degrading bacterium Enterobacterium sp. DNB-S2 and polydopamine (PDA)-coated potassium-solubilizing bacterium Paenibacillus sp. KT. The results showed that KPSB was able to simultaneously remove DBP and increase the soil available potassium (K) content. PDA has good biocompatibility and shielding effect, and the strain KT coated by it has more complete cell membrane and stronger ability to secrete low molecular weight organic acids to promote K solubilisation. The Fe3O4-modified biochar with suitable pore structure, large specific surface area and abundant functional groups could provide a good growth microenvironment for functional microorganisms and support the growth of strains while promoting the degradation of DBP. The expression of DBP-degradation-related genes was significantly increased in KPSB, which promoted the removal of DBP. In addition, KPSB has good acid and alkali resistance and a wide range of temperature adaptability, and is able to remove DBP and increase the available K content better under different environmental conditions. These results will provide new perspectives for the research of in situ soil remediation technology.

Immobilisation of arsenic and simultaneous degradation of polycyclic aromatic hydrocarbons in soil in situ by modified electrooxidation.

Improper management of wood impregnation chemicals and treated wood has led to soil contamination at many wood treatment sites, particularly with toxic substances like creosote oil and chromated copper arsenate (CCA). The simultaneous presence of these pollutants complicates the choice of soil remediation technologies, especially if they are to be applied in situ. In this laboratory study, we attempted to immobilise arsenic (As) and simultaneously degrade polycyclic aromatic hydrocarbons (PAHs) (constituents of creosote oil) by applying a modified electrochemical oxidation method. The supply of iron (Fe) amendments in contaminated soil was done using corroding Fe electrodes as an Fe source and applying an alternating polarity electrical current. Soil with a large fraction of organic matter (25%) and containing 505mgkg-1 As and 5160 mgkg-1 16-PAHs was placed in Plexiglas cells equipped with porewater samplers and an iron electrode pair connected to a power supply unit. The porewater and percolating solution were periodically sampled and analysed over an 8-week period. The modified electrochemical soil treatment led to a decrease in the total concentration of 16-PAHs in soil by 56-68%. The amount of poorly crystalline Fe oxides in the soil substantially increased, especially close to the electrodes, enabling 76-89% of As to be bound to this most reactive Fe fraction. Nevertheless, over 10% of soil As remained in the most soluble and available fraction (exchangeable), most likely due to the decline in soil redox potential over time. This study suggests that electrochemical oxidation of organic soil with mixed contaminants could be used for in situ soil remediation but needs further improvement to achieve more efficient As immobilisation.

Impact of Soil Type and Moisture Content on Microwave-Assisted Remediation of Hydrocarbon-Contaminated Soil

Volatile and semi-volatile compounds, such as petroleum hydrocarbons and equipment lubricating oils, often contaminate soil due to accidents, posing significant ecological and health risks. Traditional soil remediation methods, such as thermal desorption and bioremediation, are time-consuming and resource-intensive, prompting researchers to explore more efficient alternatives. This study investigates the effectiveness of an in situ reactor for microwave-assisted soil remediation, specifically focusing on the impact of soil type and moisture content on pollutant removal efficiency. The reactor, designed to operate within a modified household microwave oven, provides direct microwave irradiation to the soil surface, enabling precise control of heating conditions. Experiments were conducted using soil samples of varying particle sizes and moisture levels under standardized conditions (1000 W microwave power, 2.45 GHz frequency). The results show that moisture content plays a critical role in pollutant removal efficiency, with an optimal moisture content of 10 wt % enhancing microwave absorption and energy transfer, thus improving pollutant recovery. In comparison with traditional resistive heating, microwave heating achieved a faster temperature rise and higher final temperatures, significantly improving pollutant removal efficiency in a shorter time frame. This study highlights the advantages of microwave heating, including its superior energy efficiency, faster pollutant volatilization, and the potential for optimized soil remediation in real-world applications. These findings provide valuable insights for the development of more sustainable and efficient soil remediation technologies.

Bioremediation of Soil Contamination with Polycyclic Aromatic Hydrocarbons—A Review

Polycyclic aromatic hydrocarbons (PAHs) are considered hazardous pollutants due to their negative impact on the environment and human health. PAHs can accumulate and be retained in the soil, so PAH pollution is a worldwide problem. This review paper highlights the sources of PAH soil pollution, factors affecting the bioavailability of PAHs in soil, and soil bioremediation methods, as well as the advantages and limitations of the application of these methods. Aspects regarding the impact of the application of surfactants are presented in order to obtain good bioavailability during PAH bioremediation. Bioremediation techniques of soil polluted by these hydrocarbons are addressed: phytoremediation, rhizoremediation, composting, vermiremediation, micoremediation, and electrokinetic bioremediation of PAH-polluted soils. A comprehensive overview of bioremediation technologies for PAH-polluted soils is needed so that the right soil remediation technology is chosen. It has been observed the bioremediation of contaminated soils through rhizoremediation proved to be an effective process, the future of organic pollutants in interaction with plants and microbes must be researched. Vermiremediation, electrokinetic bioremediation, and microcomposting are effective processes for treating soils in situ. Phytoremediation is a sustainable and ecological method of PAH depollution. It improves soil fertility by releasing different organic matter in the soil, and it can be applied on a large scale.

Biochar Reduced the Risks of Human Bacterial Pathogens in Soil via Disturbing Quorum Sensing Mediated by Persistent Free Radicals.

Biochar has great potential in reducing the abundance of antibiotic resistance genes (ARGs) and mobile genetic elements (MGEs) from soil. However, its efficiency in removing other biological pollutants, such as human bacterial pathogens (HBPs) and virulence factor genes (VFGs), is rarely studied. Herein, by pyrolyzing rice straw (RS) and pine wood (PW) at 350 and 700 °C, we prepared a series of biochar (RS350, RS700, PW350, and PW700) and investigated their impacts on the abundance and pathogenicity of HBPs. Compared with PW biochar, RS biochar effectively reduced the abundance of HBPs by 6.3-40.1%, as well as their pathogenicity, evidenced by an 8.2-10.1% reduction in the abundance of VFGs. Mechanistically, more persistent free radicals (PFRs) were formed in RS biochar than that of PW biochar during pyrolysis, and PFRs triggered the degradation of N-butyryl-l-homoserine lactone (C4-HSL) from 1.05 to 0.68 ng/kg, thereby disturbing the quorum sensing (QS) of HBPs. Once the QS was disturbed, the communications among HBPs were hindered, and their virulence factors were reduced, which ultimately lowered the abundance and pathogenicity of HBPs. Collectively, our study provides insights into the role of biochar in decreasing the risks of HBPs, which is significant in the development of biochar-based technologies for soil remediation.

Measures and effects on soil Cd remediation and safe rice production: a meta-analysis of 10-year Chinese patents

Rice is the staple food for 1/3 of the world’s population, but soil pollution with cadmium (Cd) is harmful to rice production and human health. Therefore, how to reduce the Cd content in rice grains is a hot topic worldwide. However, so far, little is known about Cd remediation technologies for paddy soils from the perspective of patents. Therefore, a meta-analysis was performed to assess the effects of measures based on 1402 observations from 336 patents from 2011 to 2021. The spatio-temporal analysis showed that the number of patents was positively related to the general economic development of the country, but hardly related to the regional economy or the level of provincal Cd pollution. The meta-analysis showed that the overall effect of Cd reduction was slightly higher for combined technologies (59%) than for single technologies (57%). Among all technology classifications, soil applications, which are mainly based on nutritional elements, were the most commonly used technology that could reduce the Cd content in rice grains by 57%. The plant biotechnology was the most effective and could reduce Cd content in rice grains by 76%. Further analysis showed that macronutrients (calcium, phosphorus, and sulfur) were preferred in soil amendments, while micronutrients (silicon, zinc, and selenium) were preferred in foliar amendments. NRAMP5 and HMA3 were the most important genes for manipulating Cd uptake in rice, while Bacillus and Pseudomonas were the most important bacterial taxa for bioremediation of Cd. Overall, this study compiled data on Cd remediation of paddy soil from 10 years of Chinese patents, providing a theoretical basis for better production of low Cd crops and protection of human health.

Enhanced phytoremediation of cadmium-contaminated soil using chelating agents and plant growth regulators: effect and mechanism.

The heavy metal cadmium (Cd) is a major threat to food safety and human health. Phytoremediation is the most widely used remediation technology, and how to improve the remediation efficiency of phytoremediation has become a key issue. In this study, we constructed an intensive phytoremediation technology for remediation of Cd-contaminated soil with biodegradable chelating agent and plant growth regulator combined with maize and investigated the mechanism of this technology. The results showed that the best remediation effect was achieved in the treatment with 10-6 mol l-1 gibberellic acid (GA3) and 6 mmol kg-1 aspartate diethoxysuccinic acid (AES) combined with maize. In this treatment, the total biomass and extraction efficiency of maize were 3.6 and 8.67 times higher than those of the control, respectively, and the antioxidant enzyme activities of maize were also increased. The soil was enriched with dominant bacterial genera that promote plant growth and metabolism and tolerance to heavy metal stress, which in turn promoted maize growth and Cd accumulation. Structural equation modelling results indicated a large effect of plant Cd concentration and plant antioxidant enzyme activity on plant Cd extraction. The enhanced phytoremediation technology showed good potential for safe use of Cd-contaminated soil.

Nickel accumulation in plants from the Shebenik Mountain massif, Albania

AbstractHyperaccumulators are unusual plants that accumulate specific metals or metalloids in their living tissues to concentrations that may be hundreds or thousands of times greater than those normal for most plants. Hyperaccumulator plants are of practical importance as they can be used in soil remediation technologies. The Shebenik Mountain massif, located on the eastern border of Albania, hosts a wide diversity of rare and endemic plant species, including nickel hyperaccumulators. The aim of this study was to evaluate the taxa present on the Shebenik Mt. in relation to soil conditions and to test their potential for phytomining in a replicated field trial. Previous morphological and karyological analyses of material from field collections across ultramafic outcrops of the Shebenik resulted in the identification of the following nickel hyperaccumulator taxa: Odontarrhena chalcidica (Janka) Španiel & al., Odontarrhena smolikana subsp. glabra (Nyár.) Španiel & al., Odontarrhena rigida (Nyár.) L. Cecchi & Selvi, and Bornmuellera baldaccii (Degen) Heywood. In addition, a species of the genus Noccaea, formerly referred to Noccaea ochroleuca (Boiss. & Heldr.) F.K. Mey, but likely belonging to a still undescribed taxon, was also collected. An in situ replicated trial was undertaken to evaluate the potential for phytomining of three nickel (Ni) hyperaccumulators collected in the Shebenik Mt. Measurement of aboveground biomass, analysis of nickel in the biomass, and analyses of plant‐available nickel in the soil allowed calculation of bioaccumulation and phytoextraction yield. This provides a realistic evaluation of the efficacy of the plant taxa in hyperaccumulating nickel and their potential use for phytoextraction/phytomining technologies.

The study on the coupled influence of water saturation on heat and mass transfer processes within porous media under CW laser irradiation

Continuous wave (CW) laser irradiation induces temperature changes in various phases within porous media, accompanied by phase change and gas transport. Water saturation is a crucial factor influencing this context's moisture and heat transfer process. This paper addresses this issue by establishing a theoretical model for CW laser irradiation on unsaturated porous media. Through experiments and simulations, it studies the effects of different water saturations on heat and mass transfer under laser irradiation. The results indicate that the critical depth reflects the influence of water saturation under laser irradiation on the distribution of solid-phase temperature in both time and space dimensions. Specifically, an increase in water saturation enhances the uniformity of solid-phase temperature distribution, while the gas temperature exhibits a similar distribution pattern. For mass transfer processes, it increases the evaporation rate and Darcy velocity of porous media within the effective range of laser irradiation. Lower water saturation facilitates phase change processes and accelerates gas transport rates. Importantly, this trend remains consistent even with the emergence of dry-saturation zones. Additionally, the decrease in water saturation has a coupled promoting effect on gas temperature and mass transfer processes. Lowering water saturation can increase gas temperature and consequently enhance mass transfer processes. Simultaneously, enhancing mass transfer processes benefits heat exchange between the two phases. In the four sets of experiments, the conformity of the surface temperature rise curves obtained from experiments and simulations is good, indicating that the model can accurately reflect the temperature rise patterns of sand particles. In summary, this work provides valuable research results on the effects of different water saturations on laser irradiation-induced temperature rise, phase change, and gas and moisture transport within porous media. It lays a specific theoretical foundation for laser soil remediation technology.

Modeling and simulation of a multi source microwave heating of soil based on PSO-BPNN

Due to rapid industrialization, accumulation of organic pollutants in the soil has been an increasing menace, having detrimental effect on crop yields, toxicity to flora and fauna, and environment in total. Microwave soil remediation technology, has garnered a significant attention in the field of thermal degradation of organic-polluted soil. However, the high-temperature remediation often involve the use of microwave devices with multiple sources, leading to competing and coupling effects, significantly impacting heating efficiency. Therefore, an attempt was made to develop a multiple source microwave device with adjustable inputs for soil heating, to design adjustment schemes for multiple input units. A multi-physics field model consistent with the testing apparatus was developed and utilized to generate the temperature for 625 different adjustment schemes. To further refine and to optimize the adjustment schemes a PSO-BPNN model was integrated and utilized. The simulation results were utilized to predict the most effective adjustment scheme, and was tested. The model potentially serves to estimate the optimal adjustment scheme for multiple source microwave inputs for effective heating of soil.

Intermittent anaerobic-aerobic biopiling for remediating energetic compound-contaminated soils

Demolishing obsolete ammunition and live fire training, along with other military activities, contaminated military sites with energetic compounds (ECs), are raising human concerns. Biopiling is a green and sustainable technology for soil remediation due to its low cost and minimal secondary pollution. This study investigated the effects of various bio-stimulants in enhancing intermittent anaerobic-aerobic biopiling for ECs degradation in soil. The results showed that intermittent anaerobic-aerobic biopiling with municipal sludge, livestock and poultry manure, and agricultural and forestry wastes degraded 93.7 % 2,4,6-trinitrotoluene (TNT), 79.5 % hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), and 92.0 % octahydro-1,3,5,7-tetranitro −1,3,5,7-tetrazocine (HMX) in 15 days. Correlation analysis of the energetic compounds showed that the TNT concentration and its reduction products changed conversely under anaerobic conditions, indicating a faster TNT reduction. Analysis based on the Kyoto Encyclopedia of Genes and Genomes (KEGG) database revealed an increase in the abundance of genes (nemA &porA) associated with nitrotoluene reduction. This study demonstrated that bio-stimulants composed of a mixture of municipal sludge, manure, and soil conditioner (SLA) could improve the physicochemical properties of the biopiling system and the microbial community structure, promoting the growth of Firmicutes that respond for the degradation of energetic compounds, including the influence of functional genes for TNT degradation.

Study on heat and mass transfer characteristics of porous media with different pore structures under continuous wave laser irradiation

The pore structure determined by porosity and particle size will directly affect the remediation efficiency of thermal treatment on contaminated soil. To investigate the remediation capability of continuous wave laser soil remediation technology on soils with different pore structures, this paper establishes a heat and mass transfer model within unsaturated porous media under laser irradiation. Four pore structures were simulated, and the model’s reliability was experimentally validated. Under laser irradiation, energy exchange between the solid and gas phases has a minimal effect on the solid phase temperature. The temperature distribution of the solid phase in the four samples is similar, with the differences primarily arising from moisture content. Interface energy exchange dominated the rise in the temperature of the gas. The intrinsic Nusselt numbers for the four samples were 3.5, 4.4, 4.9, and 6.2, respectively. Laser irradiation causes the Nusselt number to decrease over time, but the relative magnitudes of the Nusselt numbers for the four samples remain unchanged. From the perspective of solid phase temperature, the capability of laser remediation for soils with different pore structures is similar. From the standpoint of gas temperature, the Nusselt number is decisive. However, considering the complex coupling relationship between gas temperature rise and Darcy velocity and evaporation rate, the influence of water saturation and intrinsic permeability cannot be ignored. The research findings can provide a theoretical basis and analytical methods for the efficient laser remediation of soils with different pore structures.

Zinc oxide/graphene oxide nanocomposites specifically remediated Cd-contaminated soil via reduction of bioavailability and ecotoxicity of Cd

From both environment and health perspectives, sustainable management of ever-growing soil contamination by heavy metal is posing a serious global concern. The potential ecotoxicity of cadmium (Cd) to soil and ecosystem seriously threatens human health. Developing efficient, specific, and long-term remediation technology for Cd-contaminated soil is impending to synchronously minimize the bioavailability and ecotoxicity of Cd. In the present study, zinc oxide/graphene oxide nanocomposite (ZnO/GO) was developed as a novel amendment for remediating Cd-contaminated soil. Our results showed that ZnO/GO effectively decreased the available soil Cd content, and increased pH and cation exchange capacity (CEC) in both Cd-spiked standard soil and Cd-contaminated mine field soil through the interaction between ZnO/GO and soil organic acids. Using Caenorhabditis elegans (C. elegans) as a model organism for soil safety evaluation, ZnO/GO was further proved to decrease the ecotoxicity of Cd-contaminated soil. Specifically, ZnO/GO promoted Cd excretion and declined Cd storage in C. elegans by increasing the expression of gene ttm-1 and decreasing the level of gene cdf-2, which were responsible for Cd transportation and Cd accumulation, respectively. Moreover, the efficacy of ZnO/GO in remediating the properties and ecotoxicity of Cd-contaminated soil increased gradually with the time gradient, and could maintain a long-term effect after reaching the optimal remediation efficiency. Our findings established a specific and long-term strategy to simultaneously improve soil properties and reduce ecotoxicity of Cd-contaminated soil, which might provide new insights into the potential application of ZnO/GO in soil remediation for both ecosystem and human health.

Phytoremediation of soils contaminated as a result of military and anthropogenic impact

Military conflicts and anthropogenic accidents cause significant soil contamination with heavy metals, oil products, pesticides, and other toxic substances. The purpose of this study was to highlight the factors of influence of military-anthropogenic load on soils and to analyse the available methods of their remediation. The study summarised the available and promising phytoremediation methods with an assessment of their impact on soil contamination by chemicals that are typical pollutants during military conflicts. The study summarised, classified, and compared the groups of pollutants that are most common during military operations; analysed the impact of pollutants on the fertile soil layer and their mobility; and analysed the available remediation methods. It was found that the available soil remediation technologies, which can be used individually or in combination, provide the necessary tools to address the problem of chemical contamination of soils due to toxic products such as explosive derivatives and heavy metals. The degree of economic feasibility was considered, which, accordingly, suggested that soil phytoremediation may be the most economically feasible under certain conditions. This opens wide possibilities for further investigations, where the synergy of ecology, economics, and agrobiology will enable the development of mechanisms for optimising soil phytoremediation methods, considering their type, profile, and intended use. An algorithm of actions for remediation of soils as a result of military-anthropogenic load was proposed, which includes a related set of related actions on zoning, demining, assessment, and return of land to industrial use. The findings of this study can be used to clean industrial areas that have been contaminated during production processes or accidents
