Abstract
Glycosidic bond of C-glycosides is difficult to be broken due to its chemical stability. Screening specific microbe from microbiota is a practical way to deglycosylate these compounds. In this study, a new strain W974-1 which is capable of cleaving C-glycosidic bonds was isolated from human gut microbiota by spread plate method. It deglycosylates flavonoid 8-C-glycosides such as orientin and vitexin to their aglycones with the enzymes secreted outside the bacterial cells. This strain was identified as Enterococcus avium by 16S rDNA sequencing, physiological and biochemical characterization.
