The invention discloses bacillus subtilis capable of degrading gossypol. The bacillus subtilis is bacillus subtilis BLCC1-0039, and is preserved on November 22, 2016 in the China Center for Type Culture Collection, called as CCTCC for short and located at Luojia Hill, Wuchang, Wuhan, with the preservation number of CCTCC NO: M 2016663. According to the bacillus subtilis, free gossypol can be degraded without any additional carbon sources in a culture medium only containing cottonseed meal, so that the gossypol degradation cost is greatly reduced; in addition, the bacillus subtilis has a gossypol degradation rate capable of reaching 97.81 percent under the conditions of an inoculation amount of 2 percent and fermentation culture time of 48 h, and the free gossypol can be rapidly and efficiently degraded; and moreover, neutral proteases and acid-soluble proteins can be produced by cottonseed meal fermentation, the enzyme activity of the neutral proteases can maximally reach 4,101 U/g, and the content of the acid-soluble proteins can reach 26.96 percent.
