Bifidobacterium was isolated and described in 1899 by Henry Tissier at the Pasteur Institute, Paris, France. It is a Gram-positive bacterium and inhabits the intestinal tracts of humans and animals. Morphologically, bifidobacteria are non-motile, asporogenous, pleomorphic rods of variable appearance, somewhat curved and clubbed, and often branched. Bifidobacterium species are able to utilise a wide range of mono- and disaccharides as well as oligosaccharides due to their enzyme system. Unlike lactic acid bacteria or other micro-organisms, glucose (hexose) metabolism in bifidobacteria is unique; it is often referred to as the ‘bifidus pathway’ (fructose-6-phosphate phosphor-ketolase (F6PPK), Theoretically, through the bifidus pathway, 1 mol lactic and 1.5 mol acetic acid are generated from the fermentation of 1 mol of glucose.
