Summary: Caproate, which can be produced through microbial chain elongation, shows great potential as a carbon-neutral alternative to fossil-based products. However, its production performance needs improvement for industrial applications. This study found that the addition of powdered activated carbon (PAC) significantly enhanced the production, yield, and selectivity of caproate. PAC promoted ethanol oxidation and improved the efficiency of the reverse beta oxidation (RBO) pathway, leading to increased caproate synthesis. Additionally, PAC affected the microbial community, enriching caproate-producing bacteria and eliminating irrelevant ones. Metagenomic analysis revealed that PAC up-regulated key enzyme-encoding genes responsible for ethanol oxidation and RBO pathway, thus improving caproate production. This study provides insights into the mechanism of PAC promotion of caproate generation, laying the foundation for large-scale production of caproate.

Summary: Research on biogas-producing microbial communities aims to optimize the anaerobic digestion process and biogas output. The Lachnospiraceae species play a key role in the acidogenesis during the process. The specific strain M3/9(T) possesses genes for protein degradation and amino acid fermentation. Comparison of its genome with Anaerotignum strains revealed genomic diversity. Additionally, M3/9(T) was detected in the intestines of mammals, particularly abundant in goat feces used as substrate for biogas production.

Summary: The analysis of metagenome data based on the recovery of draft genomes (MAG) has become increasingly important in microbiome research. This study focuses on strategies for recovering MAG sequences from time series metagenome surveys of full-scale activated sludge microbial communities. The authors generate MAG catalogs using multiple techniques and assess the strengths and weaknesses of each approach. They obtain nearly 9,100 draft genomes, with around 3,100 non-redundant genomic clusters. The study highlights the implications of these findings for genome-resolved metagenomics on complex communities.

Summary: This study used Trichoderma and activated sludge to construct combined activated sludge (TAS) and employed a metagenomic approach to investigate the shift in microbial community structure and function of TAS under amoxicillin stress. The findings revealed that increased abundance of certain genes contributed to the reduction in total phosphorus removal by TAS, while increased abundance of specific bacterial phyla improved TP removal. Furthermore, antibiotic inactivation has become the primary antibiotic resistance mechanism in TAS.

Summary: This study used a metagenomic approach to investigate the diversity and metabolic potential of Chloroflexi in three environmentally different bioreactors. The genomes of 17 new Chloroflexi species were assembled, two of which are proposed as new Candidatus genus. Common metabolic features were found in these genomes, including anaerobic metabolism, fermentative pathways, and genes coding for hydrolytic enzymes. The analysis also indicated a potential role of Chloroflexi in nitrogen conversion and adhesion.

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.
