Summary: This study focused on decomposing lignocellulosic biomass into monosaccharides using chemical and biological pretreatments, followed by long-term fermentation/co-fermentation for bioethanol production. Results showed high sugar utilization efficiency and bioethanol yield in the first cycle, but a decline in bioethanol production in subsequent cycles. The use of immobilized yeasts for co-fermentation was effective in improving bioethanol production from pretreated lignocellulosic biomass.

Summary: This study focuses on converting waste agricultural biomass to bioethanol through enzymatic hydrolysis and saccharification. Cellulase from Aspergillus niger was immobilized in Fe3O4/GO/CS nanocomposites to enhance its stability and efficiency. The immobilized cellulase exhibited high thermal stability and retained activity even after multiple cycles. Wheat bran and rice bran were pretreated and enzymatically hydrolyzed to obtain glucose, which was then fermented to produce ethanol. The study demonstrates the potential of utilizing lignocellulosic biomass for bioethanol production.

Summary: With the development of offshore petroleum resources, the problem of petroleum leakage accidents has become urgent. In order to improve the remediation effect of immobilized petroleum-degrading bacteria beads on petroleum-polluted seawater, a mobile bioreactor was designed. The influence of environmental factors on the physical and chemical properties of the immobilized bacteria beads in the bioreactor was investigated by changing the salinity and pH of the input water. Alginate lyase showed more binding sites with calcium alginate at a pH of 8.0 and a salinity of 30, resulting in the shortest penetration time of the bioreactor.

Summary: The nirC gene encoding the nitrite channel of E. coli K12 was successfully cloned and expressed in E. coli BL21 cells. The purified NirC monomer showed selective permeability to nitrite ions, with higher resistance to other anions compared to bacterial aquaporin. The permeability of NirC for nitrite was found to be about 10 times higher than that of aquaporin. The study also provided insights into the 3D model and channel characteristics of NirC.

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.
