Summary: The conversion of lignocellulose into monosaccharides is crucial for biofuel production. Enzymatic degradation is efficient and can lead to the production of valuable industrial enzymes, but challenges remain in the commercial production of thermostable cellulases and xylanases. The review focuses on recent advancements in isolating, manufacturing, and enhancing the activity of these enzymes from thermophilic and hyperthermophilic microbes using genetic engineering for economic production.

Summary: De-oiled grease trap waste is suitable for anaerobic digestion treatment. Different temperature conditions showed distinct responses to the waste, with mesophilic digestion demonstrating higher tolerance loading. Recovery of biogas production took longer in hyperthermophilic digestion compared to thermophilic digestion, with different concentrations of long chain fatty acids affecting the processes. Food waste with composite fractions was observed to be favorable for biogas production in the hyperthermophilic digester. Residual lipid concentrations were higher in the hyperthermophilic digestion compared to other conditions, indicating different responses to lipid loading. Additionally, composite substrates helped alleviate inhibition from long chain fatty acids by converting them into shorter chain length fatty acids.

Summary: The aim of this study was to remove refractory organics and nitrogen from high-temperature anaerobic digestate food waste effluent. Iron-based materials were used to enhance the performance of thermophilic hydrolysis-acidification. Magnetite showed the best strengthening effect and the coupling system achieved high nitrate removal efficiency and reduced the fluorescence intensity of refractory organics. Microbiological analysis showed that magnetite increased the relative abundance of hydrolytic acidifying bacteria.

Summary: This study investigates the production of biodiesel from food waste and domestic wastewater using the oleaginous yeast Rhodosporidium toruloides under non-sterile conditions. The research shows that utilizing the mixture of effluents from local food waste treatment facilities and domestic wastewater can enhance the yield of biolipid production and wastewater treatment efficiency. The optimized hydrolysis process also enables the separation of waste oil without the need for solvents, and the resulting biolipid can meet the quality standards for biodiesel production.

Summary: A hybrid anaerobic membrane bioreactor (Hy-AnMBR) was developed with the incorporation of polyurethane sponge carriers to mitigate membrane fouling. The results showed that the addition of sponge carriers reduced solid concentration and improved filtration performance. SEM analysis indicated that the cake layer fouling in Hy-AnMBR was less than the control AnMBR. CLSM analysis revealed that sponge carriers mitigated pore-blocking and reduced total membrane resistance compared to the control. Chemical cleaning was essential for pollutant removal and membrane permeability recovery.

Summary: In order to reduce costs and increase ethanol production, low-value non-sterile feedstocks can be used, and measures such as acid washing, maintaining low pH, and microaerobic conditions during fermentation can be employed. Creating symbiotic communities of lactic acid bacteria and ethanol producers can lead to more robust and competitive ethanol yields.

Summary: A study conducted in Neffatia, Tunisia, on a soil classified as Arenosol revealed that factors such as organic matter mineralization, salt accumulation, and low rainfall affect soil characteristics. The presence of roots also influenced particle size distributions, indicating the interaction between tamarisk shrubs and the environment in forming phytogenic dunes. Chemical and spectroscopic analyses further showed that tamarisk plant residues contribute to soil organic matter accumulation and characteristics, with stable organic matter closely resembling plant components and being resistant to degradation.

Summary: This paper demonstrated the growth ability of twelve algae-microbial consortia when a pig slurry-derived wastewater was used as growth substrate. The nutrient recovery, biochemical composition, fatty acid and amino acid profiles of these consortia were evaluated and compared. The study found three consortia with the best growth rates, high carbohydrates and lipid contents, and low protein and essential amino acid contents, making them potential candidates for further applications.

Summary: The performance and composition of eight microalgal communities cultivated in two different thin-layer photobioreactor designs were investigated. The study found that Chlorella vulgaris showed robustness in both designs, while reactor type and inoculum brought variability. Eukaryotic microalgae led to a more stable community, while RWs showed higher variability and did not favor eukaryotic microalgae. The reactor design also had an effect on the nitrogen cycle.

Summary: Biorefineries aim to maximize resource recovery from organic wastes, including mollusc and seafood leftovers. This study evaluated different scenarios of biorefineries fed by mollusc and fish wastes to determine the most profitable approach. The results showed that fish waste-based biorefineries had the highest revenue and shortest payback period, while including mollusc waste increased total income. The profitability of biorefineries depended on the selling price of protein hydrolysates, but also incurred high operating costs, emphasizing the importance of producing high-quality hydrolysates in an economic and sustainable way.

Summary: This paper compared the growth ability and nutrient uptake ability of algae-microbial consortia (ACs) under mixotrophic and photoautotrophic cultivation modes. The results showed that mixotrophic cultivation had higher growth rates and nitrogen uptake, as well as significant phosphorus and organic carbon removal rates. The composition of amino acids and fatty acids in ACs did not change with different cultivation modes, but the mixotrophic mode increased the content of essential amino acids, providing potential for AC_5 and AC_4 to be used as local protein feed supplements.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
