A bile salt-resistant derivative of Bifidobacterium animals has an altered fermentation pattern when grown on glucose and maltose

Article Abstract:

Differences in growth and fermentation patterns of the strain Bifidobacterium animalis subsp. lactis IPLA 4549 and its bile-resistant derivative B. animalis subsp. lactis 4549Ox in medium containing glucose or maltose as the carbon source is analyzed. Results suggest a shift in the catabolism of carbohydrates promoted by the acquisition of bile resistance that might cause changes in the redox potential and improvements in the cellular ATP yields.

Screening of exopolysaccharide-producing Lactobacillus and Bifidobacterium strains isolated from the human intestinal microbiota

Article Abstract:

Seventeen percent of human intestinal Lactobacillus and Bifidobacterium strains are exopolysaccharide (EPS) producers are detected by using phenotypic approaches. It shows that only 7 percent harbored genes related to the synthesis of heteropolysaccharides.
