| Popis: | The utilization of 1-kestose (GF(2)) and nystose (GF(3)), the main components of fructooligosaccharides (FOS), by Lactobacillus and Bacteroides species was examined. Of seven Lactobacillus and five Bacteroides strains that utilized FOS, L. salivarius, L. rhamnosus, L. casei, and L. gasseri utilized only GF(2), whereas L. acidophilus and all the Bacteroides strains utilized both GF(2) and GF(3). Only the strains able to utilize both GF(2) and GF(3) had β-fructosidase activity in the culture supernatants. The culture supernatants of the Lactobacillus strains had higher β-fructosidase activity for GF(2) than for GF(3), whereas those of the Bacteroides strains had higher activity for GF(3) than for GF(2). Furthermore, β-fructosidase activity of the culture supernatants of the Lactobacillus cells grown in the GF(3) medium was much higher than that of the cells grown in the GF(2) medium, whereas the activity of the culture supernatants of the Bacteroides cells grown in the GF(3) medium was almost the same as that of the cells grown in the GF(2) medium. These results indicate that Lactobacillus species metabolize FOS in a different way from that of Bacteroides species. |
