Summary: Waste generation from food manufacturing facilities poses serious hazards to the environment, including environmental degradation, water pollution, and land pollution. This study investigates the use of food processing waste as an organic carbon source for the growth of Chlorella vulgaris. By combining food processing waste powders with BG-11 medium, the algal growth and biochemical content were improved, with higher biomass concentration and increased lipid, protein, and carbohydrate contents. This research suggests that an integrated culture system using food processing waste can generate energy while improving the bio-composition of microalgae biomass.

Summary: This study demonstrates for the first time that ordinary residents can correctly conduct household-level indoor composting to manage urban kitchen waste at the source. Results show that the composting temperature decreases with the decline of biodegradable organic substances, and the physiochemical characteristics of the compost vary significantly towards maturation. Continuous organic humification also occurs during indoor composting.

Summary: The prodigiosin-producing strain Serratia marcescens BWL1001 showed maximum yield of prodigiosin under optimal conditions of using soybean oil as carbon source and peptone as nitrogen source. An in situ extractive continuous fermentation strategy using soybean oil as the carbon source and extractant was developed, leading to increased prodigiosin yield and reduced consumption of traditional organic solvent. Prodigiosin produced by BWL1001 exhibited significant algicidal activity against Microcystis aeruginosa, promoting its application in inhibiting harmful algal blooms.

Summary: The extensive decoration of backbones is a major factor that leads to enzymatic resistance in hemicellulose and other branched polysaccharides. Debranching enzymes are currently the main strategy used to overcome this recalcitrance. Carbohydrate-binding modules (CBMs) are contiguous amino acid sequences that can aid in the binding of enzymes to various carbohydrates, thus facilitating enzymatic hydrolysis. III and IV CBMs, characterized by their preference for branched polysaccharides, play a key role in enhancing the hydrolysis of substrates with side chains.

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.
