Summary: Three bacterial strains were isolated from activated sludge adapted to degrade pyridine and quinoline simultaneously, with Rhodococcus ruber demonstrating the fastest kinetics. Combining R. ruber with one or both of the Bacillus strains further increased the biodegradation kinetics. The three strains together significantly reduced the time needed for complete biodegradation compared to using R. ruber alone.

Summary: This study investigated the biodegradation of quinoline by Achromobacter sp. strain JWJ-09 in an inorganic salt medium. The strain showed strong degradability and degraded quinoline through the 8-hydroxycoumarin metabolic pathway. The addition of methanol facilitated quinoline degradation and the maximum specific growth rate and substrate inhibition coefficient were higher than those observed by other researchers. Moreover, the strain was successfully used to treat quinoline-containing wastewater with high removal efficiency and biological enhancement effect.

Summary: Anaerobic biodegradation of toxic compounds in industrial wastewater is an attractive solution for energy and resource recovery, but faces challenges due to low kinetics compared to aerobic processes. Research on anaerobic phenol degradation focuses on microbiological and technological aspects to enhance competitiveness, with a gap still existing between aerobic and anaerobic performance. Efforts are needed to develop powerful technologies and effective strategies to improve the anaerobic process and move towards more sustainable wastewater treatment.

Summary: Bioaugmentation was used to obtain a microbiome capable of degrading polycyclic aromatic hydrocarbons (PAHs). The study found that acclimating microorganisms to soil supplemented with phenanthrene led to the enrichment of PAH-degrading bacteria, including Actinobacteriota and genera such as Streptomyces, Rhodococcus, Nocardioides, Sphingomonas, and Mycobacterium. The degradation efficiency of phenanthrene in aqueous and soil cultures inoculated with phenanthrene-acclimated soil was found to be high. This research provides theoretical and practical support for the bioremediation of PAHs in the environment.

Summary: Polycyclic aromatic hydrocarbons (PAHs) are widely present organic pollutants in the environment, and bioremediation is considered to be an effective method for their degradation. In this study, a new strain of Diaphorobacter sp. called MNS-0 was found to be capable of degrading various PAHs. The strain exhibited tolerance to high concentrations of NaCl and alkaline conditions, while maintaining its degradation activity. Therefore, it can be potentially used for the bioremediation of PAHs pollution even in harsh environments such as saponification wastewater.

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.
