NOVELTY - A Bacillus subtilis strain (CGMCC 3374) capable of degrading organic phosphorus pesticide, is new.    USE - The B.subtilis strain is useful for degrading organic phosphorus pesticide (claimed) deposited on plant leaves, preferably oilseed rape leaves.    ADVANTAGE - The environment is protected and safety of food is improved.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for producing microbial inoculum of the B.subtilis strain, which involves preparing culture medium (1 l) using (in g) peptone (10), yeast (5), sodium chloride (5) and agar agar (20), adding water to the above-cited raw materials to make up to 1 l and adjusting the pH to 7-7.5, preparing strain activation medium (1 l) using peptone (10), yeast (5) and sodium chloride (5), adding water to the above-cited raw materials to make up to 1 l and adjusting the pH to 7-7.5, preparing seed culture medium (10 l) using magnesium sulfate (1), potassium dihydrogen phosphate (5), sodium chloride (5), dipotassium hydrogen phosphate (15), sucrose (100) and peptone (50), adding water to the above-cited raw materials to make up to 10 l and adjusting the pH to 7-7.5, preparing fermentation culture medium (200 l) using magnesium sulfate (20), potassium dihydrogen phosphate (100), sodium chloride (100), dipotassium hydrogen phosphate (300), sucrose (12 kg) and ammonium sulfate (0.8 kg), adding water to the above-cited raw materials to make up to 200 l and adjusting the pH to 7-7.5, sterilizing the culture media for 15-30 minutes at 121 degrees C, inoculating the B.subtilis strain into the culture medium, picking single colony for culturing twice at 30 degrees C, inoculating the single colony into the strain activation medium, culturing for 12-24 hours at 30 degrees C by shaking at a speed of 150-200 revolutions per minute (rpm), inoculating 5-10% of the activated strain into fermentation kettle filled with the seed culture medium, culturing for 12-24 hours at 25-37 degrees C by ventilating air to obtain liquid seed, inoculating 5-10% of the liquid seed into fermentation kettle filled with fermentation culture medium, culturing for 18-60 hours at 25-37 degrees C by ventilating air to obtain active culture, calculating the number of bacteria in the culture liquid, performing ultrafiltration and concentration to regulate the number of bacteria to 1010 colony-forming unit (CFU)/ml, adding (in %mass): glycine (0.3-1) and glycerin (0.5-5) to the culture liquid, preserving the obtained microbial inoculum in bottle, and using the microbial inoculum by diluting the liquid containing the strain to 500-1000 times.
