Abstract
Acid resistant bifidobacteria, particularly the strains Bifidobacterium infantis CNCM I-372, Bifidobacterium bifidum CNCM I-373 and Bifidobacterium breve CNCM I-374, are cultured in a semisynthetic or synthetic lactic medium. The culture compositions are resistant to oxygen and acid and have a survival level of at least 1:10 after 30 days at a pH of 4.0 at 5.degree. C. and thus are utilized in acidified food products, such as acidified milks and yogurts, having a pH of from 4.0 to 4.6.
