The growth rates of four Bifidobacterium strains were compared in two different culture media containing either 1-kestose (GF2) or nystose (GF3), the main components of fructooligosaccharides (FOS). Of the four Bifidobacterium strains examined, the growth rates of B. longum ATCC 15707T and B. catenulatum ATCC 27539 in the GF2 medium were higher than those in the GF3 medium, whereas the growth rate of B. pseudocatenulatum ATCC 27919T in the GF2 medium was lower than that in the GF3 medium. The growth rate of B. adolescentis ATCC 15705 was the same in both media.
