Brief description:

Bifidobacteria are Gram-positive irregular rods. They do not form endospores. Note the club-shaped or branched ends of the cells. Their metabolism is strictly anaerobic and fermentative, yielding a mixture of lactic acid and acetic acid. This acidification is thought to be beneficial to humans by restricting the growth of potential pathogens. "Bifid-supplemented" products are on the market (see links below).
