Polyphenols Bioactive Metabolites, and Their Anti-Biofilm and Neuroprotective Potential

Area of Science:

• Microbiology
• Nutrition Science
• Neuroscience

Background:

• Polyphenols, found in plant foods, possess antioxidant and anti-inflammatory properties.
• Gut microbiota modify polyphenols into bioactive metabolites that benefit host health.
• These metabolites influence host-microbe interactions and neurophysiological functions through the gut-brain axis.

Purpose of the Study:

• To review the transformation of polyphenols by the gut microbiome.
• To highlight the microbial metabolism, anti-biofilm activity, and neuroprotective effects of polyphenol metabolites.
• To underscore the potential impact of understanding these metabolites in food science and biotechnology.

Main Methods:

• Literature review on polyphenol microbial transformation.
• Analysis of studies on the biological activities of polyphenol metabolites.
• Synthesis of current knowledge on the gut-brain axis and polyphenol metabolism.

Main Results:

• Gut microbiota significantly transform dietary polyphenols at varying rates.
• Polyphenol metabolites exhibit anti-biofilm properties against pathogens.
• These metabolites demonstrate neuroprotective potential by modulating gut-brain axis signaling.

Conclusions:

• Microbial transformation of polyphenols yields bioactive metabolites crucial for host health.
• Further research into polyphenol metabolite properties can drive innovation in food science and biotechnology.
