The aim of the study is to screen the strain resources capable of degrading tannins. Utilising tannin-rich persimmon peel as the raw material, tannin-degrading strains were screened. The morphology, growth performance, antibacterial properties, tolerance to high temperatures and low pH, as well as the effect on tannin removal from persimmon peel, were investigated. Strain SP102 was identified as Bacillus velezensis. This strain reached the stationary phase within 10h, inhibited Fusarium graminearum, and showed no inhibition of lactic acid bacteria. It exhibited good tolerance to high temperatures and low pH. The removal rate of tannins in persimmon peel by SP102 reached 56.62%. B. velezensis SP102 can degrade tannins, and improve the quality of non-grain feed, in addition to exhibiting broad application prospects.
