| 摘 要： | 红谷霉素是链霉菌702发酵后所产的一种生物活性物质，具有较强抗细菌活性。研究表明，红谷霉素对大肠杆菌的最低抑菌浓度为40mg/L，对枯草芽胞杆菌的最低抑菌浓度为0.08mg/L。红谷霉素在微生物生长迟滞期添加比在其它生长阶段添加抑菌效果更好，红谷霉素对热和紫外比较稳定。通过与其他防腐剂的抑菌效果比较表明，红谷霉素对细菌的抑菌效果优于比较的防腐剂。

| Abstract: | Honggumycin,which was a bioactive compound obtained by the fermentation broth of Streptomyces 702,showed a significant antibacterial activity.The antibacterial activity of honggumycin against Bacillus subtilis and Escherichin coli was determined in culture medium.The result showed that the minimal inhibitory concentration(MIC)of honggymycin against Bacillus subtilis and Escherichin coli were 0.08mg/L and 40mg/L,respectively.A better bacterial growth inhibition by honggumycin was observed during the lag phase than that during other phases.Honggumycin has stability to heating and UV irradiation.Furthermore,the bacteriostatic effect of honggumycin was better than other preservatives by evaluating the antibacterial activities of honggumycin and other preservatives. |
