In this study, the effects of various buffers and ionic strengths on the immobilization of Candida rugosa and Rhizopus oryzae lipases were investigated to enhance the activities of the immobilized lipases Among. the various buffers, the optimal buffers and ionic strength for the immobilization of C rugosa and R. oryzae lipases were determined to be a mixture of 0.25 M MOPs and sodium phosphate buffer (pH 6.5). Moreover, the activities of immobilized C. rugosa and R. oryzae lipases under their optimal conditions were 3756.11 and 2845.21 U/g matrix, respectively. Furthermore, the activity of immobilized lipases increased by approximately 4.13 and 3.1 times after 24 h, respectively. Finally, the activities of the immobilized lipases were maintained at levels greater than 90% of their original activities after ten reuses and at levels greater than 60% of their original activities after twenty reuses.

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.

Machine learning-based prediction of methane production from lignocellulosic wastes

Chao Song, Fanfan Cai, Shuang Yang, Ligong Wang, Guangqing Liu, Chang Chen

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.
