Eurotium cristatum is a potential probiotic fungus that is used to enhance Fuzhuan tea quality through fermentation and could reduce obesity by modulating gut dysbiosis. This study aimed to investigate the effects and possible mechanisms of killed E. cristatum (KEC) and its polysaccharides (ECP) in ulcerative colitis (UC) relief. KEC and ECP were administered to mice with dextran sulfate sodium-induced UC. The results showed that UC severity, intestinal inflammation, and tight junction protein levels were greatly improved. Furthermore, 16S rRNA sequencing results showed that Escherichia coli , Enterococcus faecium , Clostridium perfringens , Bacteroides caccae , Rothia aeria , and Prevotella melaninogenica were depleted, while Alistipes finegoldii and Bacteroides stercorirosoris were enriched. A fecal microbial transplantation trial confirmed that KEC and ECP ameliorated UC by regulating gut dysbiosis. Thus, this research suggests that KEC and ECP are novel, potent, food-based anti-inflammatory agents that relieve UC by modulating gut dysbiosis.
