Isolation, screening and identification of endophytic antibiotic bacteria from Jun jujube

Abstract:

Jiaocheng Jun jujube (Zizyphus jujube cv. Jiaocheng Junzao) was selected as the material to isolate endophytic bacteria. 18 strains of endophytic bacteria were obtained and their antibiotic activity against pathogenic fungi and Oomycetes were evaluated in this study. The antagonistic effects showed that 5 of them expressed antibiotic activity on Colletotrichum gloeosporides, Alternaria alternata, Fusarium oxysporium, Alternarial longipes, Pyricularia oryzae, Rhizoctonia solani, Sclerotinia schinseng and Bipolaris sorokiniana to some extent. And morphological performance, physiological and chemical characteristics of 5 antibiotic bacteria were observed.
