Summary: In this study, the batch reproducibility of a sulfonic acid functionalized carbonaceous material (SAFACAM) as a catalyst for biodiesel production from inedible feedstock Jatropha curcas oil (JCO) was comprehensively verified. The catalyst is environmentally friendly and can potentially reduce the overall biodiesel production cost by converting inexpensive raw materials. Through a central composite design approach using response surface methodology, a high conversion rate of 98.7% was achieved. The chemically satisfactory composition of the biodiesel product, the reusability of the catalyst, and the enhanced performance using microwave heating were demonstrated.

Summary: Mixing jatropha oil and palm oil can reduce production steps and generate biodiesel with desired cold-flow and stability properties. Using ultrasound-assisted transesterification (UT) significantly reduces reaction time compared to conventional alkaline transesterification (CT). Increasing the proportion of jatropha oil can improve the fluid dynamics of biodiesel.

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.
