Breeding of sorghum hybrids for solid biofuel

Purpose. Today, the search, research and implementation of new technologies for the production of solid fuel is important for the agro-industrial complex and renewable energy. Sorghum is considered as a strategic crop in the provision of feedstock for bioenergy and reclamation of degraded soils. The purpose of the study was to study and select the material for the creation of high-yielding hybrids of sugar and grain sorghum for the production of solid biofuel.
 Materials and methods. The two-year results of the sorghum variety test at the Synelnykivska Experimental Station are highlighted. 68 samples were studied. They had a yield of green mass in the range of 23–79 t/ha.
 Results. F1 hybrids (Nyzk.93s x Karlykove 45) formed the highest average yield of green mass — 65.2 t/ha; F1(Early776s x Karlykove 45) — 61.4 t/ha and F1(Dn71s x Karlykove 45) — 60.1 t/ha. The yield of hybrids Mammoth and F1(A158x Karlykove 45) was slightly lower, and amounted to 53.3 and 52.8 t/ha, respectively. F1 (Nyzkorosle 93s x Karlykove 45) stood out according to the average yield of dry matter of green mass — 17.6 t/ha; F1 (Dn17s x Karlykove 45) — 13.8 t/ha. According to the average indicators of the yield of solid fuel from 1 ha, the combinations F1 (Nyzk.93s x Karlykove 45) were the best — 12 t/ha; F1 (Dn17s x Karlykove 45) — 8.2 t/ha; F1 (Early 776s x Karlykov 45) — 7.9 t/ha. The best indicators in terms of energy output were the following combinations: F1(Low 93s x Karlykove 45) — 197.7 Gj/ha, F1(Dn71s x Karlykove 45) –135.5 Gj/ha, F1(Early 776s x Karlykove 45) — 129 Gj/ha.
 Conclusions. High-yielding sorghum hybrids are the most economical and energetically expedient measures to provide feedstock for the bioenergy industry. A selected hybrid for the bioenergy application F1 (Nyzkorosle 93s x Karlykove 45) differs from the standard in terms of productivity and manufacturability. The value of the Karlykove 45 variety as a pollinator for the creation of hybrids for solid biofuel was also clarified. The agricultural sector of Ukraine has enough potential resources for biofuel production.

Characterization of a Thermophilic and Inhibitor-Tolerant GH1 β-Glucosidase Present in a Hot Spring

β-glucosidase is a key enzyme in the degradation of lignocellulosic biomass, which is responsible for the conversion of oligosaccharides from cellulose hydrolysates to glucose. However, its required high temperatures and the presence of inhibitors have limited its use in industry. In this study, a new β-glucosidase gene, named thbg2, was obtained from the metagenome Ruidian Hot Spring, Tengchong City, Yunnan Province, southwestern China. The gene was synthesized, cloned, heterologously expressed, and enzymatically characterized. Its optimum temperature and pH were 60 °C and pH 5.6, respectively. ThBg2 exhibited more than 60% relative activity in temperatures ranging from 40 °C to 70 °C and across a pH of 4.0–6.6. It maintained 100% relative activity after incubation at either 50 °C for 24 h or 60 °C for 12 h and more than 80% residual activity after incubation at pH 4.0–6.0 for 24 h. Moreover, it maintained more than 80% relative activity in the presence of heavy metal ions, ethanol, SDS etc. Furthermore, glucose yields from corn stalks increased by 20% after ThBg2 (0.05 mg/mL) was added to the commercial cellulase reaction system. Overall, this work identified a thermophilic and inhibitor-tolerant β-glucosidase with potential applications in commercial lignocellulose utilization and the bioenergy industry.

Increase of the morpho-physiological responses of sugarcane plants in vitro (Saccharum spp. hybrids) using sodium silicate

Sugarcane (Saccharum spp. hybrids) is used as raw material in the agri-food and bioenergy industries. Plant tissue culture (PTC) allows production of many propagules in a relatively short time and limited space. Silicon (Si) is considered a non-essential element, and studies have demonstrated a positive impact on the development of plants obtained through PTC. This study aimed to evaluate the bio-stimulant effect of sodium silicate (Na2SiO3) on the in vitro propagation of sugarcane (CP 72-2086 and Mex 69-290). Plant tips were established for each variety. The shoots obtained were then cultivated in an MS medium supplemented with different concentrations of Na2SiO3 (0, 2.5, 5.0, and 10.0 mg L−1). After 30 d, morphometric analysis, quantification of photosynthetic pigments, and stomatal index measurements were performed. The results showed that 10.0 mg L−1 of Na2SiO3 had a positive effect on the morphology of both varieties. The CP 72-2086 variety had a 0.5 number of shoots, 6.36 leaves and 5.8 roots more compared to the control. In contrast, the Mex 69-290 variety had more sizable proportion of shoot length (1.42 times), root length (2.20 times), and dry weight (1.33 times) compared to the control. However, 2.5 and 5.0 mg L−1 of Na2SiO3 decreased the responses of variables evaluated in both varieties compared to the highest concentration. While the addition of Na2SiO3 in both varieties had a bio-stimulant effect on the content of photosynthetic pigments. Results obtained suggest that Na2SiO3 can be used as a bio-stimulant agent during the commercial micropropagation of sugarcane hybrids.

Achieving prediction of starch in cassava (Manihot esculenta Crantz) by data fusion of Vis-NIR and Mid-NIR spectroscopy via machine learning

Cassava is an important crop for both the food and bio-energy industries, serving as a primary carbohydrate source and a staple food. Knowledge of the starch content (SC) is a key parameter index its quality. Non-destructive measurement of SC is needed to track the same tubers to study behaviours of SC accumulation in cassava tubers, which benefit for breeders in discovering a good variety and farmer to indicating harvesting period. This paper involves the prediction of cassava tuber starch content (SC) using multiple near infrared (NIR) spectrometers, aiming to measure SC in fresh cassava tuber. This study applies both portable NIR spectrometers at 570–1031 nm and 860 – 1760 nm. The best results of the model which developed provided R2p and RPD were 0.69 and 1.80 for VIS-NIR region. Meanwhile, the Mid-NIR region provided poor performance with R2p and RPD of 0.46 and 1.36, respectively. Therefore, this study aims to assess whether it was better for predicting SC if the model was developed using combined selected significant wavelength from both VIS-NIR and Mid-NIR regions using machine learning. Genetics algorithm (GA) and variables important projection (VIP) were used for selecting significant wavelength. Selected wavelengths were combined and then generate calibration models via machine learning (ML). The results of the SC model developed using NIR spectra from selected wavelength with SV regression method had the highest performance, with R2c and RMSEc of 0.88 and 1.28%. Meanwhile, the R2p, RMSEp, and RPD of 0.74, 1.86% and 1.97, respectively. Then, the best calibration model was used to measure the unknown sample which corrected from a different harvest season. The external test set provided R2p, RMSEp were 0.88 and 1.38%. The results indicate that combination of NIR with different region can achieve.

Biotechnological investigation of Pediastrum boryanum and Desmodesmus subspicatus microalgae species for a potential application in bioenergy

The production of photosynthetic microalgae is a promising ecological advantage for obtaining carbon credits. This paper addresses cultivation and preparation, growth analysis, physicochemical characterization (X-ray diffraction-XRD, Fourier transform infrared-FTIR, scanning electron microscopy-SEM, and energy dispersive spectroscopy-EDS), and thermal behavior (thermogravimetry-TG, derivative thermogravimetry-DTG, and differential scanning calorimetry-DSC) of two microalgae, namely Pediastrum boryanum-PB (CH007) and Desmodesmus subspicatus-DS (AEE431E) for a potential application as an energy resource. Regarding the former, the literature reports no specific study on the species, which shows high lipid productivity and fast growth. A synthetic culture medium (Walter culture-WC) was subjected to variations in pH, luminosity, and maximum growth reached in 12 and 13 days for PB and DS, respectively. TG/DTG curves identified the main thermal degradation stages, i.e., dehydration (DS (24.68–158.68 °C) and PB (20.06–116.18 °C)), devolatilization (DS (166.34–543.00 °C) and PB (128.22–493.93 °C)), and gasification or carbonization (DS (>550 °C) and PB (>500 °C)), and DSC curves revealed two endothermic events, an exothermic one for DS, and only one endothermic event and an exothermic one for PB. XRD patterns showed a cellulose crystallinity index (CI) for DS (22.54 %) and PB (28.82 %), confirming the predominance of amorphous regions. SEM images detected external epidermis for DS and some interconnected pores for PB. The FTIR spectra identified functional groups (lipids, proteins, and carbohydrates) and CO, CO, OH, CH, and C-O-C linkages, and EDS and ICP-OES identified the main organic, inorganic, and metallic elements. The microalgae species displayed characteristics similar to those of the other biomasses in the bioenergy industry, enabling their use in thermoconversion processes for biofuel production and considering some socioenvironmental aspects.

Outdoor cultivation of microalgae in a medium enriched with poultry droppings for biomass production

Microalgae require nutrients and optimal pH for good growth and metabolite production. Microalgae biomass has various applications in food and feed, pharmaceuticals, bio-energy, aquaculture, cosmetics and other related industries. However, the cost of media represents a significant percentage of the total production cost. The aim of this work was therefore, to develop a cheap medium for efficient outdoor cultivation of microalgae and to find the optimum pH for biomass production. Three Chlorella species designated A, B and C were isolated from three stagnant water bodies at Amoke Lane, University market road in Nsukka town by using BG-11 enriched with poultry droppings. Poultry droppings medium was prepared by drying under the sunlight for 5 days. The dried poultry droppings were crushed into a fine powder and 200 g was weighed and soaked in 1000 ml of distilled water for 3 days and filtered using a muslin cloth. A mixture of the poultry droppings medium and the conventional BG-11 medium was prepared by mixing equal volume of each medium. The growth and biomass productivity of the three local isolates in BG-11 medium were compared with those in poultry medium, and a mixture of poultry and BG-11 media. The results showed that the growth of the three isolates in poultry medium alone were significantly higher than the values obtained in BG-11 and a mixture of BG-11 and poultry medium (p< 0.05). With poultry medium, the maximum optical densities of the cultures were 2.10± 0.07, 2.56± 0.09 and 3.35± 0.11 for isolates A, B, and C respectively. However, with a mixture of BG-11 and poultry medium, the maximum optical densities were 0.83± 0.01, 1.67± 0.05 and 0.57± 0.02 respectively. BG-11 supported the least growth of the three isolates, giving maximum optical densities of 0.38± 0.01, 0.42± 0.03 and 0.52± 0.02 respectively. All the three isolates had their best growth in poultry medium at pH of 5.0. The results show that poultry medium, which is cheap and can be easily prepared from poultry droppings, is very good for cultivation of some species of microalgae.

Analysis of the Fuel Properties of the Seed Shell of the Neem Plant (Azadirachta indica)

The energetic potential of the seed shell of the Neem plant (Azadirachta indica) was investigated using proximate analysis, Higher Heating Value (HHV), thermal analysis (TG-DTG and DSC) in inert and oxidative atmospheres, and X-ray fluorescence (XRF). The results of ash (3.80% ± 0.44), volatile matter (81.76% ± 1.30), fixed carbon (14.44% ± 1.74), and estimated HHV (18.791 MJ/kg: average value) are compatible with other biomasses already used as fuels in the bioenergy industry. Thermograms showed three main degradation events in synthetic air and two in nitrogen, attributed to the moisture, release of volatile materials, and decomposition of hemicellulose, cellulose, and lignin. The elements positively detected by the XRF were Ca, K, S, P, Fe, Ti, Zn, Rb, and Sr.

Performance Evaluation for Cohesionless Soil Stabilized with Lignin and Polymerized Lignin

Abstract Lignin is a natural copolymer found in plants that is a major waste from bioenergy and paper industries. In this study, comprehensive laboratory testing programs were carried out to evaluate the strength improvements and water resistance of soil after being stabilized by lignin and polymerized lignin. The chemical polymerization of pre-treated lignin involves a process of linking short lignin molecules to form longer ones and consuming hydrophilic functional groups to improve its stability under wet conditions. Various testing combinations were considered, including four lignin or polymerized lignin contents (0, 6, 8, and 10 %) and four lime contents (0, 2, 4, and 6 %). The results show that lignin-stabilized soil will take at least 14 days to reach maximum strength, whereas the minimum curing period is 21 days for soil stabilized with polymerized lignin. The optimum dosage is 8 % when lignin or polymerized lignin is used for soil stabilization. Polymerized lignin can provide approximately 10 to 20 % more strength improvement than lignin; however, lime seems work better with lignin than polymerized lignin when added as a strength booster. The water soaking tests showed that polymerized lignin has better moisture resistance than lignin, and additional lime can further improve the performance of stabilized soil with respect to water susceptibility. However, the strength of specimens cannot fully recover, decreasing slightly after each dry–wet cycle for both specimens treated by lignin and polymerized lignin. The total decrease is about 5∼10 % after two cycles. The temperature and pH value control and oxygen supply approach used in this study will be an important reference for future studies.

Biochar as a Versatile Resource for Achieving Sustainability in Agri-food Chains

The agriculture sector generates a significant quantity of waste. These wastes, when mismanaged, can cause environmental issues like air, water, and soil pollution. Thus, the upcycling of agricultural wastes especially for bioenergy production would be highly advantageous. Biofuels, including biochar, biogas, biodiesel, and bioethanol, are eco-friendly fuels owing a significant contribution to the bioenergy industry. Biochar, a carbon-rich substance prepared from a wide range of feedstocks, can be produced from agricultural wastes via pyrolysis and has numerous applications. When added to soil, biochar enhances soil fertility by acting as a soil conditioner. It can also be used to purify air and wastewater and/or used for carbon sequestering, in the textile and construction industries. Moreover, biochar can also be used in the food products such as charcoal-based ice cream, and cookies besides being an animal feed improver. Furthermore, biochar has potential applications in the cosmetic industry and can address issues such as climate change, energy shortages, and food security. The use of agricultural wastes for biochar production can be a tool for low-cost bioenergy production, which could improve the financial status of local farmers. The current review emphasizes the potential of biochar as a versatile resource for achieving sustainability in agri-food chains by recycling generated waste.

Accelerating the development of a sustainable bioenergy portfolio through stable isotopes

AbstractBioenergy could help limit global warming to 2°C above pre‐industrial levels while supplying almost a fourth of the world's renewable energy needs by 2050. However, the deployment of bioenergy raises concerns that adoption at meaningful scales may lead to unintended negative environmental consequences. Meanwhile, the full consolidation of a bioenergy industry is currently challenged by a sufficient, resilient, and resource‐efficient biomass supply and an effective conversion process. Here, we provide a comprehensive analysis of how stable isotope approaches have accelerated the development of a robust bioeconomy by advancing knowledge about environmental sustainability, feedstock development, and biological conversion. We show that advances in stable isotope research have generated crucial information to (1) gain mechanistic insight into the potential of bioenergy crops to mitigate climate change as well as their impact on water and nutrient cycling; (2) develop high‐yielding, resilient feedstocks that produce high‐value bioproducts in planta; and (3) engineer microbes to enhance feedstock conversion to bioenergy products. Further, we highlight knowledge gaps that could benefit from future research facilitated by stable isotope approaches. We conclude that advances in mechanistic knowledge and innovations within the field of stable isotopes in cross‐disciplinary research actions will greatly contribute to breaking down the barriers to establishing a robust bioeconomy.

Litsea Males Are Better Adapted to Pb Stress Than Females by Modulating Photosynthesis and Pb Subcellular Distribution

Litsea cubeba Pers., a dioecious species, is an important tree species for the bioenergy industry with great potential for lead (Pb)-polluted soil phytoremediation. However, the sex-specific morphological and physiological characteristics of L. cubeba under Pb stress remain largely unknown. In this study, L. cubeba was used as a study model to identify sex differences in leaf traits, chlorophyll, photosynthetic gas parameters, chlorophyll fluorescence, Pb subcellular distribution, and photosynthesis-related nutrient contents in chloroplasts and cell nuclei under three different Pb concentrations [0 (CK), 1 (P1), 2 (P2), and 3 (P3) mmol/kg]. The results indicate that Pb stress significantly decreases photosynthetic leaf pigments in both sexes, mainly caused by changes in Ca, Mg, and Mn contents. Furthermore, L. cubeba male plants exhibited greater adaptability to Pb stress by enlarging their leaf area, enhancing photosynthesis and excess light energy in the form of heat dissipation when compared to female plants. Notably, we observed that more Pb reached the organelle fraction and damaged chloroplasts and mitochondria in female leaves under high-level Pb treatments compared to those of the opposite sex. Transcriptome analysis demonstrated that Pb stress could significantly up-regulate more genes involved in photosynthetic antenna proteins and photosynthesis pathways in male leaves than in female leaves. Taken together, L. cubeba male plants are clearly more resistant to Pb toxicity than female plants—at least under the described Pb treatments—which is most likely due to differences in Pb allocation. This research offers a theoretical foundation for the utilization of male and female L. cubeba as suitable plants for the remediation of Pb-polluted soil.

Effect of Torrefaction on the Physiochemical Properties of White Spruce Sawdust for Biofuel Production

Torrefaction pretreatment is a mild form of pyrolysis that has the potential to produce a high-quality raw material for making biofuel that serves as a replacement for coal in the bioenergy industry. Microwave-assisted torrefaction was conducted on white spruce sawdust (WSS) at temperatures of 200 °C, 250 °C, and 300 °C and retention times of 5 min, 7 min, and 9 min in an inert environment. The torrefaction process produces a solid carbon, commonly known as biochar, and condensable (torrefaction liquid (TL)) and non-condensable gases. In this study, torrefaction characteristics were investigated to observe its effects on the thermal and physiochemical properties of the pellets produced. During the torrefaction process, a significant mass loss associated with the decomposition of hemicellulose was observed. The hemicellulose content drastically reduced to approximately 1.8% and the cellulose content was reduced by approximately 10%, while the lignin gained approximately 35% as the severity increased. This led to an improvement in the higher heating value (HHV), hydrophobicity, bulk, particle density, pellet dimensional stability, and pellet density. However, the pellet tensile strength decreased as the torrefaction severity increased. Pellet tensile strength is a critical indicator of biomass pellets that expresses the force required to crush or damage a pellet. Therefore, to enhance the tensile strength of the pellets, the introduction of a binder was necessary. Torrefaction liquid and sawdust were used as additives at different proportions during pelletization. The addition of binders (torrefaction liquid and sawdust) to the pellet formulation increased the tensile strength of the torrefied WSS by approximately 50%. The OH groups in the biomass break down to a limited degree due to dehydration. This hinders the formation of H bonds, thereby increasing the chances that the pretreated biomass will become hydrophobic. The SEM graphs showed that the torrefied WSS pellets demonstrated more firmly glued surfaces with fewer pores spaces when set side by side with the raw pellets. The thermogravimetric analysis conducted showed that the torrefaction of WSS slightly reduced its thermal stability.

Oil spill remediation by biochar derived from bio-energy industries with a pilot-scale approach during the X-Press Pearl maritime disaster

Most traditional oil spill clean-up techniques are still laboratory based and are expensive and fairly ineffective. This study investigated the capacity of biochars derived from bio-energy industries in oil spill remediation with a pilot-testing. Three different biochars from bio-energy industries, Embilipitya (EBC), Mahiyanganaya (MBC), and Cinnamon Wood Biochar (CWBC) were assessed for the removal of Heavy Fuel Oil (HFO) at three dosages (10, 25, and 50 g L−1). Pilot-scale experiment was conducted with 100 g of biochars separately in the oil slick of X-Press Pearl shipwreck. All adsorbents exhibited rapid oil removal (within 30 min). Isotherm data were well explained by Sips isotherm model (R2 > 0.98). The pilot-scale experiment resulted oil removal for CWBC, EBC and MBC as 0.62, 1.12, and 0.67 g kg−1 respectively, even in rough sea conditions with a limited contact time (>5 min) indicates biochar's capacity in oil spill remediation as a cost-effective material.

Biologically derived copper oxide-based nanocatalyst using Moringa oleifera leaves and its applications in hydrolytic enzymes and biohydrogen production

Due to the limited availability of fossil fuels, pollution causing serious environmental issues, and their continuously rising price, the development of low-cost efficient enzymes and their implementation in biomass-based bioenergy industries are highly demanded. In the present work, phytogenic fabrication of copper oxide based nanocatalyst has been performed using moringa leaves and has been characterized using different techniques. Herein, the impact of different dosages of as-prepared nanocatalyst on fungal co-cultured cellulolytic enzyme production under co-substrate fermentation using wheat straw and sugarcane bagasse in 4:2 ratios in solid state fermentation (SSF) has been investigated. An optimal concentration of 25 ppm of nanocatalyst influenced the production of 32 IU/gds of enzyme, which showed thermal stability at 70 °C for 15 h. Additionally, enzymatic bioconversion of rice husk at 70 °C librated 41 g/L of total reducing sugars, which led to the production of 2390 mL/L of cumulative H2 in 120 h.

Review and experimental articles from the last five years were selected to recapitulate the reasons for interest in algae cultivation, for which we highlight the most valuable phytochemicals passing through their niches in the food market, their bioenergetic potential and the possible uses of algal waste biomass. In addition, we punctuate the advent of algae biorefineries. The objectives of this study were to list the main points related to interest in cultivation, drawing a parallel between the establishment of algae in the food market and its potential to establish itself in the energy market. It was concluded that the use of algae biorefineries has been used as a solution for the food, chemical and energy markets, despite the need for the development of broader research on industrial scale.

Metabolic Engineering of Microorganisms to Produce Pyruvate and Derived Compounds.

Pyruvate is a hub of various endogenous metabolic pathways, including glycolysis, TCA cycle, amino acid, and fatty acid biosynthesis. It has also been used as a precursor for pyruvate-derived compounds such as acetoin, 2,3-butanediol (2,3-BD), butanol, butyrate, and L-alanine biosynthesis. Pyruvate and derivatives are widely utilized in food, pharmaceuticals, pesticides, feed additives, and bioenergy industries. However, compounds such as pyruvate, acetoin, and butanol are often chemically synthesized from fossil feedstocks, resulting in declining fossil fuels and increasing environmental pollution. Metabolic engineering is a powerful tool for producing eco-friendly chemicals from renewable biomass resources through microbial fermentation. Here, we review and systematically summarize recent advances in the biosynthesis pathways, regulatory mechanisms, and metabolic engineering strategies for pyruvate and derivatives. Furthermore, the establishment of sustainable industrial synthesis platforms based on alternative substrates and new tools to produce these compounds is elaborated. Finally, we discuss the potential difficulties in the current metabolic engineering of pyruvate and derivatives and promising strategies for constructing efficient producers.

A Review of Biomass-to-Bioenergy Supply Chain Research Using Bibliometric Analysis and Visualization

Based on current trends and policies aimed at decarbonizing energy systems, the conversion of biomass to bioenergy has the potential to grow rapidly, but such growth depends on the development of efficient, sustainable, and competitive biomass supply chains. As a result, the biomass supply chain has stimulated the interest of a diverse group of researchers across academia, government, and industry, and there is a need to synthesize and categorize the rapidly expanding literature in this field. We conducted a literature review using advanced bibliometric analysis and visualization of 1711 peer-reviewed articles published from January 1992 to August 2022 with the aim of promoting impactful research in both growing and neglected areas of investigation. The results show that there are potential research gaps and opportunities in six critical areas: globalization of supply chain research; incorporation of uncertainty, stochasticity, and risk into supply chain models; investigation of multi-feedstock supply systems; strengthening supply chain resilience; application of inventory control methods; and broader use of machine learning and artificial intelligence in this field. By providing a holistic examination of how biomass-to-bioenergy supply chain research has grown and evolved over this period, our results and subsequent framework and recommendations can aid researchers in developing future studies and can guide stakeholder strategies to identify, diagnose, and address modern challenges that face the bioenergy industry.

In-vitro mutagenesis Approaches for Flowering Control in Sugarcane – A Review

Sugarcane (Saccharum officinarum L.) is one of the important commercial crops grown globally as a source of raw material for wide range of sugar and bio-energy industries. Crop being a member of family Poaceae, terminates its growth by flowering (arrowing). The process of flowering is highly complex process and is mediated by temperature, photoperiod, humidity, altitude and latitude besides crop genetic makeup. Though flowering is crucial for crop improvement programmes, uncontrolled flowering under commercial cultivation poses a serious problem for sugarcane farmers and millers with a considerable loss in yield and quality. Therefore, in order to device sugarcane genotype with no flowering habit enormous efforts have been made through various approaches, among them mutagenesis is one such approach wherein propagation materials will be exposed to chemicals or radiation in order to bring desirable traits. This technique looks to be the prominent crop improvement strategy for sugarcane. Hence, in this paper review we brought together the earlier work done in the field of mutation breeding in devising non-flowering sugarcane genotypes and their impacts on commercial sugarcane production.
