Synbiotic yacon juice fermented by Lactiplantibacillus plantarum QS7T attenuates dextran sodium sulfate-induced ulcerative colitis in mice.

Ulcerative colitis (UC) is a prevalent inflammatory bowel disease associated with abnormal immune responses to commensal bacteria. The study investigated the effects of synbiotic yacon juice fermented by Lactiplantibacillus plantarum QS7T (FYJ) on ameliorating UC and modulating gut microbiota in a dextran sodium sulfate (DSS)-induced colitis mouse model. FYJ intervention significantly improved body weight and colon length, reduced the disease activity index and histopathological scores, and effectively alleviated colon tissue damage compared with treatments with L.
