Urolithin A Produced by Novel Microbial Fermentation Possesses Anti-aging Effects by Improving Mitophagy and Reducing Reactive Oxygen Species in Caenorhabditis elegans

Urolithin, intestinal microbiota metabolites of ellagitannin-rich foods, exhibit anti-aging activities. However, urolithin A is significantly superior to other types of urolithin with regard to this anti-aging function. This study aimed to screen edible urolithin A-producing strains of bacteria and explore the corresponding anti-aging efficacy of fermented products produced by these strains using Caenorhabditis elegans as a model. Our results showed that the Lactobacillus plantarum strains CCFM1286, CCFM1290, and CCFM1291 converted ellagitannin to produce urolithin A; the corresponding yields of urolithin A from these strains were 15.90 ± 1.46, 24.70 ± 0.82, and 32.01 ± 0.97 μM, respectively. Furthermore, it was found that the pomegranate juice extracts fermented by the CCFM1286, CCFM1290, and CCFM1291 strains of L. plantarum could extend lifespan by 26.04 ± 0.12, 32.05 ± 0.14, and 46.33 ± 0.12%, respectively, by improving mitochondrial function and/or reducing reactive oxygen species levels. These findings highlight the potential application of this fermentation in the subsequent development of anti-aging products.

 

Comments：

The study aimed to identify edible urolithin A-producing strains of bacteria and evaluate the anti-aging efficacy of fermented products produced by these strains using Caenorhabditis elegans as a model. The results showed that the Lactobacillus plantarum strains CCFM1286, CCFM1290, and CCFM1291 converted ellagitannin to produce urolithin A, with varying yields. Fermentation of pomegranate juice extracts by these strains resulted in significant lifespan extension in C. elegans, with the highest percentage increase observed in the CCFM1291 strain. This effect was attributed to improved mitochondrial function and/or reduced reactive oxygen species levels. These findings suggest that this fermentation process has the potential for developing anti-aging products.
