Combined effects of BARLEYmax and cocoa polyphenols on colonic microbiota and bacterial metabolites in vitro

다국어 초록 (Multilingual Abstract)

BARLEYmax, a barley variety, and cocoapolyphenols (CPPs) have been reported to affect bacterialmetabolites in the colon. This study aimed to evaluate thecombined effects of BARLEYmax and CPPs supplementationon fecal microbiota in vitro using pig feces for 48 h.
The relative abundances of the family Clostridiaceae andthe genus Clostridium and ammonia–nitrogen productionwere decreased by both BARLEYmax and CPP supplementation,and there was a positive correlation betweentheir abundances and the ammonia–nitrogen concentration.
Although acetate and n-butyrate production was decreasedby CPP supplementation, their concentrations were maintainedat a higher level in the BARLEYmax ? CPP groupthan in the cellulose (control) and cellulose ? CPP groups.
Therefore, this study demonstrated that a combination ofBARLEYmax and CPPs may be beneficial in maintaininghigher short-chain fatty acid production and the eliminationof potentially harmful factors.
