Comparison of the Growth of Bifidobacteria in Two Culture Media Containing Either 1-Kestose (GF2) or Nystose (GF3)

Abstract

The growth rates of four Bifidobacterium strains were compared in two different culture media containing either 1-kestose (GF 2 ) or nystose (GF 3 ), the main components of fructooligosaccharides (FOS). Of the four Bifidobacterium strains examined, the growth rates of B. longum ATCC 15707 T and B. catenulatum ATCC 27539 in the GF 2 medium were higher than those in the GF 3 medium, whereas the growth rate of B. pseudocatenulatum ATCC 27919 T in the GF 2 medium was lower than that in the GF 3 medium. The growth rate of B. adolescentis ATCC 15705 was the same in both media.
