Beschreibung
Zusammenfassung:	The invention belongs to the technical field of agricultural microorganism application, and particularly relates to a precursor peptide of thuringin with bacteriostatic activity on several pathogenicbacteria. A separated and screened bacillus thuringiensis XY66 is secreted from the sequence of the precursor peptide, and the preservation number of the bacillus thuringiensis XY66 is CCTCC NO: M2018124. The bacillus thuringiensis can generate novel bacteriocin, and the bacteriocin is named as thuringin by the applicant. The molecular weight of the thuringin is 4, 347.93Da, and the amino acid sequence of the precursor peptide is shown as the sequence of the 1-144 base site in SEQ ID NO: 1. The separated thuringin has efficient bacteriostatic activity on various pathogenic bacteria such as streptococcus pneumoniae, listeria monocytogenes and bacillus cereus. 本发明属于农业微生物应用技术领域，具体涉及对几种病原细菌有抑菌活性的苏云金菌素的前体肽。分泌该前体肽序列的为一株分离筛选的苏云金芽胞杆菌XY66，其保藏编号为CCTCC NO：M 2018124。本发明的苏云金芽胞杆菌能产生一种新型细菌素，申请人将该细菌素命名为苏云金菌素。所述苏云金菌素的分子量为4,347.93D
