Summary: This study applied response surface methodology to optimize the liquid hot water pretreatment of sugarcane bagasse, and achieved the highest sugar yield under the pretreatment conditions of 186°C, 25 min, and solid-to-liquid ratio of 0.08. By enzymatic hydrolysis of the pretreated residuals at 20% (w/v) solid content, the obtained sugars reached 121 g/L. Through controlling the fermentation process, most of the C5 and C6 sugars were converted into succinic acid with a high conversion rate of 280 mg/g SCB. This study provides a new clue for clean and efficient biorefining of chemicals.

Summary: The NaOH catalytic ethanol pretreatment of sugarcane bagasse improved glucose yield by assisting delignification and preserving cellulose and hemicellulose. Higher temperature and longer time resulted in higher glucose yield, while the addition of Tween 80 significantly reduced enzyme usage and enzymolysis time while maintaining comparable glucose yield. This study provided an economically feasible method for generating glucose followed by fermentation and conversion to platform chemicals.

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.
