摘要： Wheat bran (WB) was solid-state fermented by either Lacticaseibacillus rhamnosus (LGG), Levilactobacillus brevis (LB) or Lactiplantibacillus plantarum (LP), respectively, and then their corresponding physicochemical and metabolic characteristics were investigated. Current study revealed fermentation of either Lacticaseibacillus rhamnosus or Lactiplantibacillus plantarum quickly generated lactic acid, but not for Levilactobacillus brevis. Importantly, all LAB fermentation promoted total phenolic acids contents, fermentation of LB-WB led to the greatest total phenolic content, followed by LGG-WB, with the least for LP-WB. Moreover, LGG fermentation significantly increased levels of oleic acid, stearic acid and phosphoenolpyruvic acid on carbon metabolism and fatty acid biosynthesis, while LB fermentation mainly increased levels of L-phenylalanine, cholecalciferol, D-gluconic acid and D-glucarate with the influence on the entire metabolic pathway. In contrast, LP fermentation significantly decreased levels of alpha-ketoglutaric acid, cis-aconitic acid on the citrate cycle (TCA cycle). This study revealed their corresponding metabolic characteristics, which might highlight potentially individual nutritional aspects.
