Mycovorax composti gen. nov., sp. nov., a member of the family Chitinophagaceae isolated from button mushroom compost.

Two Gram-stain-negative, aerobic, rod-shaped, orange-coloured bacterial strains, designated strain C216T and strain M2295, were isolated from mature mushroom compost from composting facilities in Victoria and South Australia, Australia, respectively. External structures such as flagella or pili were not observed on the cells under scanning electron microscopy. Optimal growth was found to occur at 45 °C, at pH 7.25 and in the absence of NaCl on Emerson's 350 YpSs medium. The genome sequence of strain C216T was 3 342 126 bp long with a G+C content of 40.5 mol%. Functional analysis of the genome of strain C216T revealed genes encoding chitinolytic and hemi-cellulolytic functions, with 166 predicted genes associated with carbohydrate metabolism (8.9% of the predicted genes). These functions are important for survival in the mushroom compost environment, which is rich in hemicelluloses. No antibiotic resistance genes were found in the genome sequence. The major fatty acids of strain C216T were iso-C15 : 0 (56.7%), iso-C17 : 0 3-OH (15.6%), C16 : 1 ω7c/iso-C15 : 0 2-OH (7.3%) and iso-C15 : 1 G (6.1%). The only respiratory quinone was MK-7. The major polar lipid of strain C216T was phosphatidylethanolamine, but three unidentified phospholipids, four unidentified aminophospholipids/aminolipids and one unidentified glycolipid were also detected. Phylogenetic analysis based on proteins encoded by the core genome (bac120, 120 conserved bacterial genes) showed that strain C216T forms a distinct lineage in the family Chitinophagaceae and that the closest identified relative is Niabella soli (69.69% ANI). These data demonstrate that strain C216T represents a novel genus and novel species within the family Chitinophagaceae, for which we propose the name Mycovorax composti. The type strain is C216T (=DSM 114558T=LMG 32998T).

Effects of organic amendments on nutrient and quality characteristics of Salvia fruticosa Mill at different plant growth stages

ABSTRACT Salvia (Salvia fruticosa Mill) is used in traditional medicine and in food and pharmacological industries, and as organically grown plants are preferred it is important to understand how organic soil fertilisation regimes affect the nutritional status and quality of the plant. To address this, an experiment was conducted testing the direct (in the first year) and residual (in the second year) effects of different organic nutrient inputs; control (C: untreated plants), farmyard manure (FYM), chicken manure (CM), vermicompost (VC), and spent mushroom compost (SMC). In the first year, N concentrations in the salvia were increased by 15%–46% and 8%–16%, at beginning of flowering and at full flowering, respectively, indicating a direct effect of the organic amendments. In the second year, the residual effects of the organic amendments increased N concentrations by 8%–37% at beginning of flowering. The organic amendments also affected concentrations of P at full flowering and caused increases of 6%–23% in the first year and by 6%–18% in the second year. Soil organic matter increased by 13%–16% as direct effects of the organic amendments and by 14%–24% as residual effects. Antioxidant activity, total flavonoid and phenolic concentrations of the salvia increased with applications of organic amendments. Total phenolic concentration and antioxidant activity were positively correlated with N, Mn and Mg and negatively correlated with K, Ca and P in the plant leaves. VC and SMC were the most effective amendments for enhancing total flavonoid content, antioxidant activity and plant nutrient concentrations.

Paramixta manurensis gen. nov., sp. nov., a novel member of the family Erwiniaceae producing indole-3-acetic acid isolated from mushroom compost

There are numerous species in the Erwiniaceae family that are important for agricultural and clinical purposes. Here we described the Erwiniaceae bacterium PD-1 isolated from mushroom (Pleurotus eryngii) compost. Comparative genomic and phylogenetic analyses showed that the strain PD-1 was assigned to a new genus and species, Paramixta manurensis gen. nov., sp. nov. in the family Erwiniaceae. From the average amino acid index, we identified the five AroBEKAC proteins in the shikimate pathway as a minimal set of molecular markers to reconstruct the phylogenetic tree of the Erwiniaceae species. The strain PD-1 containing annotated genes for ubiquinone and menaquinone produced a higher level of ubiquinone (Q8) than demethylmenaquinone (DMK8) and menaquinone (MK8) in anaerobic condition compared to aerobic condition, as similarly did the reference strains from the genera Mixta and Erwinia. Results from fatty acid methyl ester and numerical analyses of strain PD-1 showed a similarity to species of the genera Mixta and Winslowiella. This study revealed that the strain’s ability to utilize polyols, such as glycerol, erythritol, and d-arabitol, distinguished the strain PD-1 from the nearest relative and other type strains. The analyzed genetic markers and biochemical properties of the strain PD-1 suggest its potential role in the process of mushroom compost through the degradation of carbohydrates and polysaccharides derived from fungi and plants. Additionally, it can produce a high concentration of indole-3-acetic acid as a plant growth-promoting agent.

Impact of titanium dioxide (TiO2) nanoparticle and liquid leachate of mushroom compost on agronomic and biochemical response of marigold (Tagetes erecta L.) under saline stress.

The cultivation of ornamental horticultural crops under salinity stress has been a challenge for growers all over the world. In this study, an attempt was made for pot cultivation of Marigold (Tagetes erecta L. var. Pusa Basanti Gainda) in salt-stressed (SS) soil (150 mM) with the combined use of mushroom compost leachate (CL) and foliar application of titanium dioxide nanoparticles (TiO2-NPs). For this purpose, a total of six pot treatments, i.e., borewell water (BW; control), T1 (BW with SS), T2 (BW with SS and TiO2-NPs), T3 (CL supplemented), T4 (CL with SS), and T5 (CL with SS and TiO2-NPs) were conducted in triplicate. The results of this study showed that CL supplementation significantly (p < 0.05) improved the physicochemical i.e.,pH (14.5%), electrical conductivity (32.9%), total nitrogen (27.4%), total phosphorus (247.6%)), and nutrient (organic matter: 119.6%) profiles of soil which later helped in higher growth (30-35%) and yield (5.4-40.7%) of T. erecta. In CL-based treatments, the biochemical constituents were significantly (p < 0.05) higher than those in BW-irrigated ones. Also, the levels of selected stress defense enzymes were significantly increased under SS treatment but reduced under TiO2-NP application. Overall, it was observed that the combined application of CL and TiO2-NPs (T5 treatment) was the most helpful treatment for enhanced germination, growth, yield, biochemical parameters, and better plant enzymatic activities to cope with saline stress. This study provides a mechanistic understanding of T. erecta plants under saline stress which is crucial for the development of targeted interventions aimed at improving plant tolerance to saline conditions.

Organic mulches slightly influence the wine phenolic profile and sensory evaluation

Organic mulching offers numerous agronomical benefits, but its impact on wine quality remains unclear. This study assessed the effect of this practice on wine physicochemical, phenolic composition and sensory properties. Over four years, three organic mulches (grape pruning debris (GPD), straw (STR), and spent mushroom compost (SMC)) and two conventional practices (tillage (TILL) and herbicide (HERB)) were evaluated in two locations. Wines from mulching treatments exhibited higher pH, potassium, hue, and lower tartaric acid. Moreover, the SMC mulch treatment showed lower amounts of wine anthocyanins, flavonols and hydroxycinnamics, probably due to increased nutrient availability. However, no differences were detected in the wine sensory analysis. Therefore, organic mulches could be alternative practices to mitigate the consequences of climate change without significant impact on young wine's phenolic profile and sensory properties compared to HERB and TILL conventional soil management. However, future studies should focus on wine evolution during aging.

Bulb growth parameters of wild geophyte, giant snowdrop (Galanthus elwesii Hook. f.) in different media and nutrient solution recipes

Giant snowdrop (Galanthus elwesii Hook. f.) is reported on CITES lists as the most important wild-collected export flower bulb of Turkey. After the destruction caused by extensive collecting for many years, collection and trade have been controlled by the government since the late 1980’s. Export quotas are annually set by a technical committee, following field inspections by scientific teams. Small bulbs (under-sized) are also unintentionally collected from nature together with marketable sized bulbs (&gt; 4 cm). Low success rate at cultivation of field grown snowdrop and loss of these small bulbs reveals the necessity of the studies on soilless culture. This study aimed to select the suitable growing media and mineral nutrition for snowdrop bulb production. Under-sized (unmarketable) bulbs of Galanthus elwesii Hook. f. were cultivated in four different growing media (perlite, coco-peat, soil, or spent mushroom compost + perlite) with four different nutrient solutions. The growing media affected most of the investigated parameters (sprouting time, sprouting ratio, total weight and increase ratio, number of harvested bulbs, and bulb grades). No significant effect of nutrient solutions was determined on the parameters. Spent mushroom compost + perlite appeared to be the most effective growing media.

Effect of Composted Organic Waste on Miscanthus sinensis Andersson Energy Value

At the time of rising urbanization and population growth, the search for renewable energy sources to ensure sustainable development is of extreme importance. The aim of this research was to determine the effects of different proportions of composted organic materials, i.e., mushroom substrate and municipal waste, on Chinese silver grass (Miscanthus sinensis Andersson) energy value. A three-year field experiment was established on experimental plots in the east-central part of Poland. Various treatment combinations, each introducing 170 kg N·ha−1 to the soil, had a positive effect on the energy parameters of Chinese silver grass biomass. The highest calorific value (17,964 kJ·kg−1) was noted for plants treated with mushroom compost on its own (MSC100%).

Influence of Different Substrates on Nutrient Composition of Vermicompost and Vermiwash

The present study was conducted to evaluate the effect of different substrates on nutrient composition of vermicompost and vermiwash at Division of Soil Science, College of Agriculture, Pune during 2022-23. High density polyethylene beds of 12 X 4 X 2 feet size were used for production of vermicompost. While 200 liter capacity plastic barrels were employed for vermiwash preparation. There were five treatments of substrate combination like 25% rain tree litter (RTL) + 75% paddy straw spent mushroom compost (PSSMC); 50%tree litter+50% paddy straw spent mushroom compost (PSSMC); 75% tree litter+25% paddy straw spent mushroom compost (PSSMC); 100% rain tree litter, 100% paddy straw spent mushroom compost (PSSMC) were used for the preparation of vermicompost with earthworm Eisenia fetida and replicated four times in completely randomized block design. There were ten plastic barrels of above capacity were used for by using vermicompost prepared from different substrate combinations. The sampling, harvesting and characterization of vermiwash was done in duplicate for first and second harvest after incubation period of 15 days. Results showed that pH, EC, organic matter, C: N ratio, total nitrogen, phosphorus, potassium, iron, zinc, manganese, copper in vermicompost were significantly influenced by different proportions of rain tree litter and paddy straw spent mushroom compost. C: N ratio of vermicompost prepared by using rain tree litter and paddy straw spent mushroom compost was ranged between 9.71 and 16.19. Significantly higher total nitrogen (2.31%), phosphorus (1.185%), potassium (0.863%), iron (1072 mg kg-1), manganese (231.50 mg kg-1), zinc (254 mg kg-1) and copper (54.25 mg kg-1) were noted in vermicompost from 100% rain tree litter. Significantly high EC (total soluble salts) at first and second harvest of vermiwash was reported when 100% rain tree litter compost and vermicompost as substrate used. Further, vermiwash prepared by using vermicompost from rain tree litter reported significantly higher nitrogen (0.65 and 0.51%), phosphorus (0.33 and 0.27%) and potassium (0.27 and 0.23%) content at both harvest respectively but higher content was in first harvest. Vermiwash prepared from 100% raintree litter vermicompost reported significantly higher Fe, Mn, Zn and Cu content at both harvesting stage.

Phytostabilization of Heavy Metals and Fungal Community Response in Manganese Slag under the Mediation of Soil Amendments and Plants.

The addition of soil amendments and plants in heavy metal-contaminated soil can result in a significant impact on physicochemical properties, microbial communities and heavy metal distribution, but the specific mechanisms remain to be explored. In this study, Koelreuteria paniculata was used as a test plant, spent mushroom compost (SMC) and attapulgite (ATP) were used as amendments, and manganese slag was used as a substrate. CK (100% slag), M0 (90% slag + 5% SMC + 5% ATP) and M1 (90% slag + 5% SMC + 5% ATP, planting K. paniculata) groups were assessed in a pilot-scale experiment to explore their different impacts on phytoremediation. The results indicated that adding the amendments significantly improved the pH of the manganese slag, enhancing and maintaining its fertility and water retention. Adding the amendments and planting K. paniculata (M1) significantly reduced the bioavailability and migration of heavy metals (HMs). The loss of Mn, Pb and Zn via runoff decreased by 15.7%, 8.4% and 10.2%, respectively, compared to CK. K. paniculata recruited and enriched beneficial fungi, inhibited pathogenic fungi, and a more stable fungal community was built. This significantly improved the soil quality, promoted plant growth and mitigated heavy metal toxicity. In conclusion, this study demonstrated that the addition of SMC-ATP and planting K. paniculata showed a good phytostabilization effect in the manganese slag and further revealed the response process of the fungal community in phytoremediation.

Machine Learning Application to Optimize Spent Mushroom Compost (SMC) Biochar as Filter Media for Heavy Metal Adsorption in Abandoned Mine Water

AbstractThe surging global population strains resources, escalating pollution, and exacerbating water scarcity. Sustainable water management necessitates alternative sources such as abandoned mine water. However, these sources often contain hazardous heavy metals, like lead, copper, iron, and manganese, posing grave health and environmental risks. Conventional methods struggle to effectively treat these heavy metals in abandoned mining ponds, urging the search for cost‐efficient and sustainable solutions. Biochar, particularly from spent mushroom compost (SMC), emerges as a potent adsorbent due to its high surface area and binding groups. Yet, the variability in its efficiency remains a challenge. Conventional empirical models fail to capture the dynamic nature of adsorption processes accurately. Adopting machine learning, specifically an adaptive neuro‐fuzzy inference system (ANFIS), shows potential in predicting adsorption efficiency. This study aims to employ ANFIS to forecast SMC biochar's performance in a lab‐scale metal retention pond, providing design charts for diverse initial metal concentrations and pH levels. Validation through real cases aims to enhance accuracy and establish a framework for future heavy metal adsorption capacities. This research offers a sustainable approach to removing heavy metals from abandoned mining ponds whereas the computational modeling in optimizing SMC biochar introduces a novel approach for practical applications.

Effect of Bacillus subtilis, Soil Amendments and Microalgae Treatment on Fusarium equiseti of Turmeric (Curcuma longa L.) Prayagraj, India

Rhizome rot of turmeric caused by Fusarium equiseti emerge as a significant soil-borne threat to crop health. An experiment was conducted to evaluate the effect of Bacillus subtilis, soil amendments and microalgae treatment on Fusarium equiseti of Turmeric (Curcuma longa L). Experiment was conducted under field condition at the courtyard of department of Plant Pathology, SHUATS, Prayagraj, during kharif season of 2022. Various soil treatments including farm yard manure (FYM), spent mushroom compost (SMC), and microalgae were used, along with rhizome treatment utilizing Bacillus subtilis. The experiment was carried out in Randomized Block design (RBD) with three (3) replications. Results revealed that in the soil application, (T5) i.e., the combination of all the treatments recorded minimum disease intensity (59.26%) which was significant over other treatments and control (T0) (33.86%). To evaluate the radial growth (mm) of Fusarium equiseti in turmeric, seven botanicals from Manipur viz., Zanthoxylum acanthopodium, Phlogacanthus thyrsiformis, Solanum xanthocarpum, Centella asiatica, Drymaria cordata, Persicaria chinensis and Gynura cusimbua were investigated in vitro at 10% and 30% concentration. The antagonistic effects of various botanicals were evaluated in vitro, demonstrating inhibition of mycelial growth. Among the tested botanicals, Zanthoxylum acanthopodium inhibited the highest inhibition rate (86.27%), followed by Phlogacanthus thyrsiformis (77.45%), Solanum xanthocarpum (75.48%), Persicaria chinensis (68.62%), Drymaria cordata (65.68%), Gynura cusimbua (62.74%) with Centella asiatica displaying the lowest inhibition rate (57.84%), all at a concentration of 30%. Overall, our findings highlight the potential of integrated management strategies involving biological control agents and soil amendments for sustainable management of Fusarium equiseti in turmeric cultivation. Implementation of these strategies holds promise for improving crop health, productivity, and sustainability in turmeric production systems.

Comparative Environmental and Economic Analysis of Biomethane Production from Co-Digestion of Rice Straw and Spent Mushroom Compost: Application of Zero-Valent Iron Nanoparticles

Abstract Spent mushroom compost is one of the main potentials for biogas production. In recent years, several studies employed adding nanoparticles and alkaline pretreatment for improving biogas production. The present study is one of the pioneer studies that employ hybrid alkaline pretreatment (0, 5, and 15 mg of NaOH) and zero-valent iron nanoparticles (0, 10, 20, 30, and 40 mg) for improving the co-digestion of spent mushroom compost and rice straw. According to the results, retention time (RT) and nanoparticle (NP) concentrations have the most significant impact on biomethane production (significant at 1% probability level), while the NaOH concentration has the lowest impact on biomethane production (significant at 5% probability level) in comparison with RT and NP concentration. Also, the maximum biomethane production is related to NP40Na15 (about 200% higher than the control). The minimum cumulative biomethane production is related to NP0Na15 (about 30% lower than the control). The lowest relative environmental midpoint impact is related to NP40Na15, which was on average about 60% lower than the control. Adding NPs at high concentrations of NaOH reduces the midpoint impacts. The results of the study could lead to new, ecologically friendly biomethane production methods that make better use of agricultural and organic wastes.

EVALUATION OF MICROBIAL POTENTIAL OF RHIZOBACTERIAL ISOLATES ASSOCIATED WITH SPENT MUSHROOM COMPOST AGAINST BACTERIAL WILT OF TOMATO

Bacterial wilt, caused by the soil-borne pathogen Ralstonia solanacearum, poses a significant threat to tomato crops worldwide. This study aims to assess the microbial potential of rhizobacterial isolates obtained from spent mushroom compost in suppressing bacterial wilt of tomatoes. Spent mushroom compost is a byproduct of mushroom cultivation and is known to harbor diverse microbial communities with potential plant-beneficial properties. Tomato leaves that were contaminated were collected from a number of places in the Rawalpindi Area, Punjab, Pakistan. Rhizobacterial isolates were collected from the rhizosphere of tomato plants grown in the presence of spent mushroom compost. These isolates were then subjected to laboratory evaluations for their antagonistic activity against R. solanacearum. Selected rhizobacterial isolates were further characterized for their plant growth-promoting traits. The potential of these isolates to enhance tomato plant growth and confer resistance against bacterial wilt was evaluated through greenhouse experiments. Results indicated that certain rhizobacterial isolates exhibited substantial antagonistic activity against R. solanacearum. Additionally, these isolates demonstrated multiple plant growth-promoting traits, suggesting a potential dual role in both pathogen suppression and plant enhancement. Greenhouse experiments revealed a significant reduction in the incidence of bacterial wilt in tomato plants and increase in the growth promotion traits were observed while treated with the selected rhizobacterial isolates alone and in combination compared to control groups. The findings from this study highlight the promising role of rhizobacterial isolates associated with spent mushroom compost in managing bacterial wilt in tomatoes.

Change of core microorganisms and nitrogen conversion pathways in chicken manure composts by different substrates to reduce nitrogen losses.

Due to the rapid development of animal husbandry, the associated environmental problems cannot be ignored, with the management of livestock and poultry manure emerging as the most prominent issue. Composting technology has been widely used in livestock and poultry manure management. A deeper understanding of the nitrogen conversion process during composting offers a theoretical foundation for selecting compost substrates. In this study, the effects of sawdust (CK) and spent mushroom compost (T1) as auxiliary materials on nitrogen as well as microbial structure in the composting process when composted with chicken manure were investigated. At the end of composting, the nitrogen loss of T1 was reduced by 17.18% relative to CK. When used as a compost substrate, spent mushroom compost accelerates the succession of microbial communities within the compost pile and alters the core microbial communities within the microbial community. Bacterial genera capable of cellulose degradation (Fibrobacter, Herbinix) are new core microorganisms that influence the assimilation of nitrate reduction during compost maturation. Using spent mushroom compost as a composting substrate increased the enzyme activity of nitrogen assimilation while decreasing the enzyme activity of the denitrification pathway.

Organic amendments temporarily change arsenic speciation and bioaccessibility in a lead and arsenic co-contaminated urban soil.

Organic amendments often reduce the bioaccessibility of soil lead (Pb) but not that of soil arsenic (As). The effect of Pb on As bioaccessibility is rarely studied in co-contaminated soils. In a field study, we assessed the effect of mushroom compost, leaf compost, noncomposted biosolids, and composted biosolids amendments on As speciation in a co-contaminated (As and Pb) soil at 7, 349, and 642 days after amending soils and the change of As speciation during an in vitro bioaccessibility extraction (gastric solution, pH 2.5) using bulk X-ray absorption near-edge structure spectroscopy. Soil was contaminated by coal combustion and other diffuse sources and had low As bioaccessibility (7%-12%). Unamended soil had As(III) sorbed onto pyrite (As(III)-pyrite; ∼60%) and As(V) adsorbed onto Fe oxy(hydr)oxides (As(V)-Fh; ∼40%). In amended soils, except in composted biosolids-amended soils, at 7 days, As(V)-Fh decreased to 15%-26% and redistributed into As(III)-Fh and/or As(III)-pyrite. This transformation was most pronounced in mushroom compost amended soil resulting in a significant (46%) increase of As bioaccessibility compared to the unamended soil. Composted biosolids-amended soils had relatively stable As(V)-Fh. Lead arsenate formed during the in vitro extraction in amended soils, except in composted biosolids-amended soils. Arsenic speciation and bioaccessibility were similar in 349- and 642-day in all the amended and unamended soils. Reduction of As(V)-Fh to As(III) forms in the short term in three of the amended soils showed the potential to increase As bioaccessibility. The formation of stable lead arsenate during the in vitro extraction would counteract the short-term increase of As bioaccessibility in those amended soils.

Evaluation of White Rot Fungus to Control Growth of Escherichia coli in Cattle Manure

Biological soil amendments of animal origin, such as aqueous dairy manure, may be contaminated with microbial pathogens that can subsequently result in contaminated soil, water runoff, and crops. Multiple mitigation strategies are being evaluated to reduce these risks. Inclusion of filamentous fungus in a biofiltration system to inactivate pathogenic bacteria in aqueous dairy manure prior to land application is explored in this study as a preharvest preventative method. Of the microbes used to remediate biologically contaminated sites, ligninolytic white-rot fungi have been previously studied for their ability to degrade a wide variety of toxic or persistent environmental contaminants. Reduction of two E. coli strains (E. coli TVS355 and E. coli O157:H7 4407) was evaluated in aqueous dairy manure and PBS and in the presence of white-rot fungi Pleurotus ostreatus on three different nutrient sources (woodchips (WC), spent mushroom compost (SMC), and reticulated polyurethane foam (RPF)). Overall, E. coli TVS355 was more persistent in aqueous dairy manure and PBS, surviving for 50 days in the presence of P. ostreatus, with a final concentration of 4 log CFU/g in aqueous manure and 7 log CFU/g in PBS. However, greater (p < 0.0001) reduction of E. coli O157:H7 was observed, surviving for 50 days at an average of 4 log CFU/g in aqueous dairy manure and an average of 3 log CFU/g in PBS. Therefore, P. ostreatus has the potential to result in bacterial decay, with potential reduction observed in E. coli O157:H7. The RPF matrix showed positive results as a potential model for a nutrient limiting resource for P. ostreatus and could be the key to increased bacterial reductions if resulting in ligninolytic activity in order to seek other nutrient sources.

Possibilities of using organic wastes as a growing medium in soilless culture for cut flower rose

The possibilities of using organic wastes, such as hazelnut shells (HS), walnut shells (WS), hazelnut skins (HzS), and spent mushroom compost (SMC), as growth medium in cut flower rose cultivation in soilless substrate culture were investigated. The parameters, such as the date of cutting the flower (day), flower stem length (cm), flower stem diameter (mm), flower length (cm), flower diameter (cm), flower color, color of the top and bottom of the leaf, and yield (piece), were examined. In addition, samples taken from the growth medium at the beginning and ending stages of the experiment were analyzed. The first flowers were cut from the HzS +P medium 38 days after planting. The highest yield value (20.6 flower/plant) was obtained from SMC medium. The longest flowers (63.89 ± 0.947 cm) and the thickest stem flowers (5.86 ± 0.136 mm) were cut from the control medium. It was determined that the media also affected the flower and leaf colors. According to the results obtained, SMC and HzS+perlite mediums can be recommended as an alternative to cocopeat in the production of cut roses in soilless substrate culture.
