  • Effect of galactooligosaccharides produced by the $\beta$-galactosidase from Aapwefillua niger CAD 1 on the growth of Bifidobacterium infantis KCTC 3127 Bifidobacterium longum KCTC 3128 and Bifidobacterium bif-idum ATCC 11863 were investigated. Bifidbacterium infantis Bifidobacterium longum and Bifidobacterium bif-idum were in the logarithmic growth phase after 6hr incubation at 37$^{\circ}C$. Bifidobacterium infantis was in the stationary phase after 24hr incubation at 37$^{\circ}C$. The growth rate of B. bifidum containing galactooligo-saccharides and raffinose in MRS broth increased up to 18%, 8% and 7% compared to glucose galac-tose and lactose during 48hr incubation. The growth rate of B. infantis and B. longum contatining galacto-oligosaccharides and raffinose in MRS broth increased up to both 6% and 8% and both 13% and 10% compared to glucose and galactose during 48hr incubation.
