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.

Functional yacon juice fermented by Lactiplantibacillus plantarum QS7T: Chemical composition, flavor volatiles, and gut microbiota modulation.

To prepare functional yacon juice, this study investigates the optimal fermentation duration, shelf-life, chemical composition, and flavor volatiles of yacon juice fermented by Lactiplantibacillus plantarum QS7T capable of utilizing fructo-oligosaccharides (FOS), along with its effects on gut microbiota. The optimal fermentation period was determined as 30 h, resulting in essential parameters: 3.46 g L for total acids and a viable lactic acid bacteria (LAB) count of 2.

Comparative transcriptomic analysis reveals a potential link between sugar transporters and the diauxic growth of Weissella paramesenteroides YT175 on inulin.

Inulin, a health-promoting dietary fiber, is efficiently metabolized by Weissella paramesenteroides YT175, a beneficial bacterium. The strain demonstrated a diauxic growth pattern within 48 h, reaching an optical density at 600 nm (OD) of approximately 1.5, accompanied by a significant decrease in pH to around 4.
