Bifidobacterium bifidum is a gram-positive, anaerobic, rod-shaped bacteria species belonging to the genus Bifidobacterium.
B. bifidum is well adapted to the gut due to its ability to adhere to intestinal epithelial cells and metabolise complex carbohydrates, including host-derived glycans such as human milk oligosaccharides (HMOs).
During fermentation, B. bifidum produces short chain fatty acids such as acetate and lactate, which support gut barrier integrity and create an acidic environment that suppresses pathogenic bacteria. Some strains also modulate immune function and help maintain microbial balance. Because of these properties, B. bifidum is included in probiotic products aimed at digestive and immune health, and certain strains have been evaluated in clinical trials (Culpepper et al., 2016; Langkamp-Henken et al., 2015).
As some properties & benefits of probiotics may be strain-specific, this database provides even more detailed information at strain level. Read more about the strains that we have included from this genus below.
