We investigated the roles of extracellular sialidases (SiaBb1 and SiaBb2) in cross-feeding between sialidase-carrying Bifidobacterium bifidum and sialic acid-utilizing Bifidobacterium breve. Using 6' sialyllactose (6'SL) as a carbon source, the number of wild-type B. bifidum cells increased while that of a siabb2-inactivated strain (Δsiabb2) did not. Read More
