Growth of Bifidobacteria: Environmental Conditions and Adherence to Epithelial Cells

Abstract

Bifidobacteria were found to be a predominant components of the intestinal flora in breast-fed infants. They contribute to digestion, immunity promotion, production of vitamins (mainly of the B group) and inhibition of pathogens. The benefits of consuming milk products containing bifidobacteria are well documented Bifidobacteria have been used as probiotics in humans. More than 70 products mostly of diary origin containing bifidobacteria, are produced world wide.

Bifidobacteria are nutritionally fastidious microorganisms that require specific growth factors as only a limited number of these bacteria can grow in minimal culture condition.

The objective of this study was to investigate the effect of environmental conditions on the growth of 4 species of bifidobacteria. Adhesion of these bacteria to sheep intestinal epithelial cells was also studied.
