NOVELTY - A Bacillus cereus strain 0214 (CCTCCM 2014061), is new.    USE - The B.cereus strain 0214 having oxytetracycline-degrading ability, is useful for composting pig manure contaminated with oxytetracycline (all claimed).    ADVANTAGE - The B.cereus strain 0214 has strong adaptability and high oxytetracycline degradation rate. The method is performed cost-effectively and environmentally-friendly, and suitable for large-scale application.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) method for screening oxytetracycline-degrading bacteria, preferably B.cereus strain 0214, involves (a) preparing bacterial suspension using pig manure which is contaminated with oxytetracycline, adding the bacterial suspension to basal culture medium containing 400-500 mu g/ml cycloheximide, and performing culturing process, (b) isolating single bacterial colonies from culture, inoculating the single bacterial colonies into culture medium comprising oxytetracycline, and continually improving the concentration of the oxytetracycline in the culture medium to not less than 200 mg/l to isolate adaptive single bacterial colonies, and (c) inoculating adaptive single bacterial colonies into culture medium comprising inorganic salts, and continually improving the concentration of the oxytetracycline in the culture medium to not less than 200 mg/l to isolate bacteria having oxytetracycline degradation rate of not less than 50% and optical density (OD)600 value of not less than 0.2, where the culture medium (1 l) containing inorganic salts, comprises 0.05-0.1% sodium dihydrogen phosphate, 0.05-0.1% dipotassium phosphate and 0.1-0.2% ammonium sulfate, and the pH of the culture medium containing inorganic salts is controlled at 7-7.4; (2) composition prepared by mixing dried powder of B.cereus strain 0214 with organic matrix in a mass ratio of 1:4-1:5; (3) method for producing the composition containing B.cereus, involves (a) inoculating 2-5% seed liquid of B.cereus into culture medium in a fermenter, and performing culturing process until formation of spores reaches not less than 90% to obtain fermentation broth, (b) centrifuging the fermentation broth, removing supernatant, and adding organic matrix to precipitate, and (c) drying mixture obtained in step (b) at 30-50 degrees C until moisture content of dried product reaches 5-8%, and crushing dried product; and (4) use of B.cereus for composting pig manure contaminated with oxytetracycline. The culture medium in the fermenter comprises 6-7% soybean powder, 7-8% corn powder, 1-2% bran, 0.5-1% humic acid, 0.05-0.1% sodium dihydrogen phosphate, 0.05-0.1% dipotassium phosphate and 0.1-0.2% ammonium sulfate, where pH of the culture medium is 7-7.4 and the culture medium is sterilized at high temperature and high pressure for 15-30 minutes.
