Summary: In this study, a novel phenacetin-degrading strain PNT-23 was isolated from municipal wastewater and identified as a Rhodococcus sp. The isolated strain could completely degrade 100 mg/L phenacetin within 80 h, utilizing it as its sole carbon source for growth. Two key intermediates, N-acetyl-4-aminophenol and 4-aminophenol, were identified during the phenacetin biodegradation by strain PNT-23. This study provides new insights into phenacetin biodegradation and presents a potential candidate for its microbial removal in various environments.

Summary: Epidemiological studies have shown that long-term exposure to toxic volatile organic compounds, known as BTEX, is associated with preterm births. This study used a global chemical transport model and an epidemiological model to quantify the country-specific preterm birth rate attributable to long-term BTEX exposure in 2015. The study found that there were 2.01 million preterm births globally due to BTEX exposure, with the largest contributions from India.

Summary: Various interactions between marine cyanobacteria and heterotrophic bacteria have been studied, but the symbiotic relationships between Microcystis and heterotrophic bacteria remain unclear. In this study, it was found that Microcystis aeruginosa produces bleach-causing compounds, leading to its collapse after exponential growth, while a symbiotic bacterium, Pseudomonas sp. MAE1-K, delays the bleaching process by inactivating these compounds. Furthermore, a mutant strain of MAE1-K causing methionine deficiency promotes the bleaching process of M. aeruginosa, suggesting that methionine deficiency may induce the production of bleach-causing compounds. These findings provide insights into the symbiotic relationships between M. aeruginosa and heterotrophic bacteria and have implications for the control of cyanobacterial blooms.

Summary: Cardiovascular disease (CVD) is a global health issue, and elevated cholesterol levels are a major risk factor. Although dysbiotic gut microbiota has been linked to CVD development, the beneficial effects of a healthy microbiota in reducing cholesterol levels have not been summarized. This paper discusses the potential mechanisms of gut microbiota in lowering cholesterol levels and explores the use of probiotics in clinical studies. Furthermore, it highlights the cholesterol-lowering abilities of beneficial commensal microbes, such as Akkermansia and Bacteroides, which could be the next-generation probiotics (NGPs).
