Summary: In this study, the potential of two less explored fungal strains, Trichoderma longibrachiatum (TL) and Pycnoporus sanguineus (PS), in improving the hydrolysis and bioavailability of rice straw in anaerobic digestion (AD) was evaluated. The fungal treatment of rice straw for 10 days by TL and PS increased biogas production and reduced soluble chemical oxygen demand (sCOD). The microbial communities in treated samples showed increased diversity, contributing to better process performance and enhanced resilience against pH fluctuations.

Summary: This study investigates the possibility of utilizing biogas as a fuel for heating and power generation without desulfurization pretreatment in a bioelectrochemical system (BES). The results show that the biogas-fueled BES can be successfully started up within 36 days and the presence of hydrogen sulfide promotes both methane consumption and electricity generation. Optimal performance is achieved under bicarbonate buffer solution and 40°C conditions. Addition of sulfide and L-cysteine facilitates methane consumption and electricity generation. The dominant bacteria in the anode biofilm are Sulfurivermis, unclassified_o__Ignavibacteriales, and Lentimicrobium, while the predominant archaea are Methanobacterium, Methanosarcina, and Methanothrix. Anaerobic methane oxidation and electricity generation are closely related to sulfur metabolism, as revealed by metagenomics profiles. These findings provide a novel approach for utilizing biogas without desulfurization pretreatment.

Summary: A sequential fungal pretreatment of Miscanthus x giganteus using Ceriporiopsis subvermispora was conducted, showing enhanced cellulose digestibility in the first generation but no improvements in subsequent generations. High degradation of Miscanthus structural carbohydrates occurred in the first generation. Microbial community analysis revealed a decrease in the relative abundance of C. subvermispora, indicating the dominance of other microbes. Changes in the bacterial community may be associated with unwanted cellulose degradation in the system.

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.
