Growth-promoting Effects of N-Acetylneuraminic Acid-containing Substances on Bifidobacteria

Abstract

The use of N-acetylneuraminic acid, sialyl-lactose, and glycomacropeptide by bifidobacteria and lactobacilli, and their growthpromoting effects on B. longum, B. breve, B. bifidum, and B. infantis were investigated. The data presented here suggest that fortification with N-acetylneuraminic acid-containing substances of infant formula may provide formula-fed infants with a function that human milk possesses.
