Antagonistic bacteria for controlling the fusarium wilt of continuous cropping banana and their microbial organic fertilizer

The antagonistic bacteria for controlling the Fusarium wilt of continuous cropping bananas include strain NJN-6 and strain NJN-11, both of which belong to Bacillus subtilis and have been collected in China General Microbiological Culture Collection Center (CGMCC) with their corresponding collection numbers are CGMCC No. 3183 and CGMCC NO. 3184.

• The main biological characteristics of the Strain NJN-6 are as follows:
• Gram-positive;
• rod-shaped;
• terminal spore;
• facultative anaerobe;
• catalase-positive;
• oxidase-negative;
• V.P. reaction is positive;
• methyl red test is negative;
• the fermentation of glucose generates acid without gas;
• the fermentation of fructose generates acid and gas;
• xylose, L-arabinose and mannit can't be fermentated;
• citrate-positive;
• nitratase-positive;
• amylase-positive;
• gelatin hydrolysis-positive;
• decompose reaction of casein is positive.
