Embodiment Construction
[0018] Examples of the present invention are described below.
[0019] Activate the original seed of the microbial organophosphorus pesticide residue-degrading bacteria BTAH1 of the present invention on a petri dish, measure its degradation performance, and inoculate it on the inclined surface of a test tube for later use. The test tube seeds were inoculated into 1000ml shake flasks containing 200ml broth medium, cultured with constant temperature shaking until logarithmic phase, and prepared to inoculate seed tanks. 500 liters of seed tanks, 400 liters of feeding capacity, the medium formula is: glucose 0.8%, (NH 4 ) 2 SO 4 1%, K 2 HPO 4 0.2%, MgSO 4 0.05%, NaCl 0.01%, CaCO 3 0.3%, yeast extract 0.02%, pH 7.2-7.5. After the feeding is completed, sterilize under high pressure at 121°C, cool to 33°C, inoculate the above cultured shake flask strains into a 500-liter seed tank at an inoculum size of 10%, and cultivate until the logarithmic growth phase, with a stirring ...
