16S rDNA of broad-spectrum antagonistic strain B96-Ⅱ was amplified by PCR and sequenced.Using BLAST software,comparison results showed B96-Ⅱ was possibly identified as Bacillus subtilis combining its morphological,physiological and biochemical characteristics.In order to construct Escherichia coli-Bacillus shuttle vector containing gfp and B96-Ⅱ self promoter,digested fragments of total DNA of B96-Ⅱ that was digested by Sau3A I were ligated to pNW33N-gfp that was digested by BamH I,and the product was trans...
