Bacillus cereus with antibacterial activity against several foodborne pathogenic bacteria and bacteriocin of bacillus cereus

The invention belongs to the technical field of agricultural microbial application, and particularly relates to bacillus cereus with antibacterial activity against several foodborne pathogenic bacteria and a bacteriocin of the bacillus cereus. The bacillus cereus DDD103 is preserved in the China Center for Type Culture Collection, and the preservation number of the bacillus cereus is CCTCC NO: M 2018041. The bacillus cereus can produce the cyclic bacteriocin, and the bacteriocin is named by the applicant as cereine. The molecular weight of the cereine is 7066.89 Da, and the amino acid sequenceof a precursor peptide of the cereine is shown in SEQ ID NO: 2. The cereine has high-efficiency antibacterial activity against various foodborne pathogenic bacteria such as the bacillus cereus and Listeria monocytogenes. The high temperature resistance of the cereine is stronger, and inactivation does not occur when the cereine is treated at 100 DEG C for 30 minutes; the cereine is more tolerantto acids and alkalis, and
