摘要: Microorganisms of the genus Bifidobacterium are inhabitants diverse niches including digestive tract humans and animals. The species adolescentis, animalis, bifidum, breve longum have qualified presumption safety status granted by EFSA several strains considered probiotic, being included in functional dairy fermented products. In present work we carried out a preliminary exploration general metabolic characteristics organic acid production profiles reduced number selected from these other Bifidobacterium. use resting cells allowed obtaining fingerprints without interference metabolites accumulated during growth culture media. Acetic was most abundant formed per mol glucose consumed (from 1.07±0.03 to 1.71±0.22 mol) followed lactic 0.34±0.06 0.90±0.12 mol), with moderate differenc...
