Gut microbiota dysbiosis has been implicated in rheumatoid arthritis (RA) and influences disease progression. Although molecular and culture-independent studies revealed RA patients harbored a core microbiome and had characteristic bacterial species, the lack of cultured bacterial strains had limited investigations on their functions. This study aimed to establish an RA-originated gut microbial biobank (RAGMB) that covers and further to correlates and validates core microbial species on clinically used and diagnostic inflammation and immune indices.

Article Synopsis
  • Trichloroethylene (TCE) is a harmful chemical found in the soil, and it is hard to get rid of because of a protective layer on iron powder.
  • Scientists created a special bacteria, called Escherichia sp. F1, which helps break down TCE by releasing iron effectively.
  • With the right conditions, this new method can remove up to 86.86% of TCE in the soil in just 28 days, making it a greener way to clean the environment!

The gut commensal bacteria species are negatively associated with many metabolic diseases, and have been seen as promising next-generation probiotics. However, the cultured strain resources were limited, and their beneficial mechanisms for improving metabolic diseases have yet to be explored. In this study, we developed a method that enabled the enrichment and cultivation of strains from fecal samples.

Article Synopsis
  • Trichloroethylene (TCE) is a harmful chemical found in the environment and is recognized as a Group 1 carcinogen that affects human health and ecosystems.
  • The review discusses the different biodegradation processes for TCE, focusing on four main methods involving bacteria: anaerobic reductive dechlorination, anaerobic cometabolic reductive dichlorination, aerobic co-metabolism, and aerobic direct oxidation, with special emphasis on aerobic co-metabolism due to its effectiveness.
  • The study highlights recent advancements in enhancing TCE biodegradation using materials like zero-valent iron (ZVI) or biochar in combination with microorganisms, and outlines future research needs and challenges in both lab and field applications for better management of chlorinated
