A bile acid-degrading strain Lactobacillus plantarum GR-4 alleviates ulcerative colitis by reducing conjugated bile acid stress and protecting gut microbiota
a BAs degradation strain Lactobacillus plantarum GR-4 was isolated from traditional Chinese food. GR-4 showed deconjugation abilities in the two different BAs (69.67% for taurochenodeoxycholic acid and 98.47% for glycochenodeoxycholic acid) in vitro.
