菌株F12-11-1-2的16S rDNA序列分析及其生理生化性质研究

The 16S rDNA Sequence Analysis and Phenotypical Study of Strain F12-11-1-2

摘要:

菌株F12-11-1-2是一株从中国东海浙江海域200m的海泥中分离得到的,具有抗稻瘟霉(Pyricularia oryzae)活性。通过对菌株的形态、培养特征、生理生化特征的研究以及16S rDNA序列分析,结果表明它是一株适应了海洋环境的芽孢杆菌属(Bacillus)的枯草芽孢杆菌(Bacillus subtilis)。

Abstract:

The strain F12-11-1-2 was isolated from the East China Sea,which had antimitosis activity using Pyricularia oryzae mode.Ac- cording to phenotypical study,salt-aggregation test and 16S rDNA sequence analysis,the strain F12-11-1-2 has been identified to be Bacillus subtilis.
