一种多产色链霉菌菌株及其应用
摘要：
本发明涉及生物技术领域，公开了一种多产色链霉菌菌株及其应用。所述的多产色链霉菌菌株从临高县美台镇的健康土壤样品中分离筛选得到，命名为多产色链霉菌(Streptomyces polychromogene)G59，于2015年5月25日保藏于中国典型培养物保藏中心，地址为湖北省武汉市武汉大学内，保藏编号为CCTCC NO:M2015323。该菌株对防治香蕉长形叶斑病菌、香蕉炭疽病菌、香蕉枯萎病菌、粉蕉枯萎病菌、香蕉大灰斑病菌、荔枝炭疽病菌、芒果炭疽病菌、芒果链格孢霉叶斑病菌、芒果叶枯病等病原菌均有抑制作用；将所述的多产色链霉菌G59与甲基营养性芽孢杆菌4-L-16和枯草芽孢杆菌混合发酵制得的混合菌株发酵液对香蕉枯萎病具有显著的防治效果。
摘要（英）：

The invention belongs to the field of biotechnology, and discloses a Streptomyces polychromogene bacterial strain, and applications thereof. The Streptomyces polychromogene bacterial strain is obtained via separation and screening of healthy soil samples come from Meitai town, Lingao country, is named as Streptomyces polychromogene G59, and is preserved in China Center For Type Culture Collection on 25th, May, 2015, in Wuhan university, Wuhan, Hubei province, and preservation number is CCTCC NO:M2015323. The Streptomyces polychromogene bacterial strain possesses inhibiting effects on banana long leaf spot disease, colletotrichum musae, banana wilt, dwarf banana wilt, banana curvularia leaf spot, litchi anthracnose, mango anthracnose disease, mango alternaria leaf spot, and mango leaf blight; a mixed bacteria strain fermentation liquid prepared via mixed fermentation of Streptomyces polychromogene G59 with bacillus methylotrophicus 4-L-16 and bacillus subtilis possesses excellent treatment effects on banana wilt.
