Fecha de publicación: | 22-mar-2019 | Editor: | AIMS Press | Citación: | AIMS Microbiology 5(1): 102-116 (2019) | Resumen: | This work describes the impact of long term consumption of an isoflavone-rich dietary daily supplement on the composition and diversity of the faecal microbiota of a menopausal, equol-producing woman. Sequencing of 16S rDNA amplicons was performed on faecal samples taken at 0, 1, 3 and 6 months of treatment. Additionally, and for comparative purposes, ethidium monoazide (EMA) was used to avoid detection of DNA from dead bacteria. Members of two genera of the family Coriobacteriaceae (Eggerthella and Collinsella) were found in greater proportions at all sampling points during isoflavone supplementation. Different genera of the family Ruminococcaceae (e.g., Ruminococcus and Faecalibacterium), as well as members of the family Lachnospiraceae (Coprococcus) also underwent significant increases. For this last genus a positive correlation with the levels of equol excretion in urine was found. Currently bacterial strains known to be involved in isoflavone metabolism and equol production have been assigned to these taxa. The use of EMA dye allowed us to unravel those bacterial gut linages (e.g., Lachnospiraceae) that were more susceptible to damage. Our study contributes to the identification of microorganisms possibly involved in the production of isoflavone-desirable metabolites (such as equol), which could ultimately be isolated and further used as probiotics by people who cannot naturally benefit from isoflavones. | Versión del editor: | http://dx.doi.org/10.3934/microbiol.2019.1.102 | URI: | http://hdl.handle.net/10261/186196 | DOI: | 10.3934/microbiol.2019.1.102 | ISSN: | 2471-1888 |
