K. M. Salim Andalib, Fabliha Bashashat Rodosy, Ahsan Habib
TL;DR
This study explores gut bacteria metabolites for their potential to act as antioxidants, antimicrobials, and anticoagulants, suggesting new therapeutic applications.
Contribution
The study identifies specific gut bacteria metabolites with strong therapeutic potential, including anti-microbial and anti-thrombotic properties.
Findings
Metabolic extracts from all isolates showed strong antioxidant activity.
Metabolites from Lactobacillus rhamnosus, Priestia flexa, and Bacillus subtilis inhibited pathogenic bacterial strains.
Escherichia fergusonii metabolites were most effective in lysing blood clots compared to streptokinase.
Abstract
Gut microbial metabolism is intimately coupled to host health and disease. Recent knowledge on potential health benefits of gut microbiome lays the groundwork for development of novel therapeutic strategies. But how microbiota-derived metabolites impact on host-microbiome crosstalk remains untapped from therapeutic perspectives. In this study, six gut bacteria sourced from a fecal pool of forty healthy donors were cultured in three distinct growth media. Subsequently, the bacteria were identified through 16S rRNA gene sequencing and subjected to metabolite extraction to evaluate their anti-microbial, anti-oxidant and anti-thrombotic potential. Findings reveal strong anti-oxidant activities in the metabolic-extracts from all the isolates. Metabolites derived from Lactobacillus rhamnosus, Priestia flexa and Bacillus subtiilis inhibited the growth of clinically pathogenic strains…
