Summary: Anaerobic digestion is a biotechnology for converting organic waste into biogas, but the decreasing renewable electricity prices require alternative uses for biogas. Recent efforts have focused on developing innovative platforms for producing chemicals from CH4, with ectoine being a prominent example. This study aimed to optimize the accumulation of ectoines using mixed microbial consortia from saline environments and activated sludge, with the enrichments showing different yields under varying NaCl concentrations and incubation temperatures.

Summary: By analyzing the composition and functional potentials of soil microbiomes, this study identified specific microbial communities and genes associated with the suppression of banana Panama disease caused by Fusarium oxysporum f. sp. cubense tropical race 4 (Foc4). Pseudomonas was identified as a potential key taxon linked to pathogen suppression, and the microbiomes in suppressive soils displayed a greater incidence of genes related to quorum sensing, biofilm formation, and synthesis of antimicrobial compounds. These findings suggest the importance of specific microbial communities and functional capacities in disease suppression.

Summary: In recent years, advances in high throughput sequencing technologies have opened up new possibilities for environmental monitoring in the food processing industry. This study used whole metagenome sequencing to assess the microbiome and resistome of food processing environments from slaughterhouses, dairy processing plants, and meat processing plants. The results showed that slaughterhouses had more diverse microbiomes and resistomes, while dairy processing plants had the highest variability. Different predominant bacterial genera were found in each industry type. The study also identified the most abundant antimicrobial resistance genes, which were associated with resistance to aminoglycosides, tetracyclines, and quaternary ammonium compounds. The findings have important implications for food safety management systems.

Summary: This study investigated the relationship between microbial life strategy and energy and nutrient flux in anaerobic digestion (AD). The results showed that there was a positive correlation between microbial rrn copy number and CH4 daily production, and this correlation was weakened when feedstock complexity was reduced. Furthermore, the mean rrn expression ratio of microbial communities also exhibited similar patterns. The findings reveal a novel relationship between microbial community life strategy and the energy and nutrient flux during AD.

Summary: Through experiments, it was found that seeds may survive and contaminate the digestate during anaerobic digestion. This finding was verified in both lab-scale and full-scale reactors, and seed survival was tested in a pH-buffered water bath. The results showed that the commercial reactor was more effective in killing seeds compared to the experimental reactor and water bath treatments. While the risk of seed contamination can be reduced in non-hard-seeded species, it remains a challenge for hard-seeded species.

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.
