NOVELTY - A compound microorganism microbial inoculums is formed by mixing bacterial powder (1), bacterial powder (2) and bacterial powder (3) at a weight ratio 1:1:1, and vacuum packing. The powder (1), after respectively being cultured for 16-20 hours to cell concentration of 107 colony forming unit/ml, Geobacillus stearothermophilus and G. thermodenitrificans are mixed at a volume ratio 1:1, and a mixed liquid is introduced into a sterile liquid culture medium.    USE - Compound microorganism microbial inoculum for efficient utilization and conversion of bred poultry waste (claimed).    ADVANTAGE - The microbial inoculum can reduce bad smell of excrement in poultry farm, can reduce fly, and is good for health growth.    DETAILED DESCRIPTION - Compound microorganism microbial inoculums is formed by mixing bacterial powder (1), bacterial powder (2) and bacterial powder (3) at a weight ratio 1:1:1, and vacuum packing. The powder (1), after respectively being cultured for 16-20 hours to cell concentration of 107 colony forming unit (CFU)/ml, G. stearothermophilus and G. thermodenitrificans are mixed at a volume ratio 1:1, and a mixed liquid is introduced into a sterile liquid culture medium. The inoculum concentration is 5% (V/V), and the sterile liquid culture medium comprises corn steep liquor (0.5%), soya bean meal (3-5%), sodium chloride (0.2%) (NaCl), dipotassium hydrogen phosphate (0.1%) (K2HPO4) and potassium dihydrogen phosphate (0.075%) (KH2PO4). The initial pH is 6.5-7, the temperature is 55 degrees C and the flow rate of aseptic air is 0.2-0.3 m3/minute-m3. Stirring speed is 150-180 rpm and cocultivation is carried out for 16-18 hours. The fermented liquid is sieved by an 80-meshes filter, and the filtrate is added with porous starch (12-18 wt.%), maltodextrin (12-18 wt.%), thiocarbamide (0.1 wt.%) and polyvinylpyrrolidone (0.1 wt.%) (PVP). After spray drying, tricalcium phosphate (5 wt.%) serves as filling agent. Bacterial count is calculated by flat plate counting method, and composite powder with ratio of G. stearothermophilus to G. thermodenitrificans of 45-50:55-50 and with the viable count of 1010-1011 CFU/g is obtained. For powder (2), in the middle logarithmic phase, Bacillus licheniformis and B. atrophaeus are inoculated into a sterile liquid culture medium comprising potato starch (1%), bean pulp (0.6%), powdered corn cob, (0.8%), K2HPO4 (0.1%) and magnesium sulfate (0.1%) (MgSO4). The pH is 7, the temperature is 37 degrees C and the stirring speed is 150-180 rpm. The flow rate of aseptic air is 0.3-0.5 m3/minute-m3, and cocultivation is carried out for 28-32 hours. The fermented liquid is sieved by an 80-meshes filter, and the filtrate is added with porous starch (12-18 wt.%), maltodextrin (12-18 wt.%), thiocarbamide (0.1 wt.%) and PVP (0.1 wt.%). After spray drying, calcium chloride (5 wt.%) serves as the filling agent. The bacterial count is calculated by flat plate counting method, and composite powder with ratio of 45-50:55-50, sporulation rate of 70-80% and with viable count of 1010-1011 CFU/g is obtained. For the powder (3), in the middle logarithmic phase, Ureibacillus thermosphaericus is inoculated into sterile culture medium comprising casein peptone (1.5%), soya peptone (0.5%), NaCl (0.5%) and chicken manure soak solution (10%). A ratio of chicken manure to water is 1:10 (W/V). The pH is 7-7.5. The temperature is 55 degrees C and the stirring speed is 120-150 rpm. The flow rate of aseptic air is 0.2-0.4 m3/minute-m3, and cocultivation is carried out for 20-24 hours. The fermented liquid is sieved by an 80-meshes filter, and the filtrate is added with porous starch (12-18%), maltodextrin (12-18%), thiocarbamide (0.1%) and PVP (0.1%). After spray drying, calcium chloride (5 wt.%) serves as the filling agent. The bacterial count is calculated by the flat plate counting method, and bacterial powder with viable count of 109-1010 CFU/g is obtained. An INDEPENDENT CLAIM is included for manufacturing the compound microorganism microbial inoculum.
