STUDIES ON PILOT-SCALE FERMENTATION FOR ANTIFUNGAL POLYPEPTIDE JIEAN-PEPTIDE |
| |
Abstract: | A strain of Bacillus (Bacillus sp.ZK) has been screened from cotton plant in Xinjiang.A new antifungal peptide was isolated from its cultures,and was named Jiean-peptide.This antifungal peptide had strong antimicrobial activity to many plant pathology fungi.Jiean-peptide fermentation by Bacillus strain ZK was carried out in 1,000 L fermenter.The relationship of the growth of ZK,utilization of glucose and production of Jiean-peptide were studied.The results are valuable for industrial production of this important polypeptide. |
