TECHNOLOGY FOCUS - BIOLOGY - Preferred Components: The microbial inoculum culture liquid is prepared with viable cell count (colony forming unit)/(x 108/g(ml)) of greater than or equal to 45. The alcohol distillers are present in an amount of 0.5-1.2 liters. Preferred Method: The culture liquid preparation step comprises mixing 15-20 g/l of glucose, 2-5 g/l of yeast extract, 8-10 g/l of peptone and 15-20 g/l of agar with 1000 ml of distilled water, sterilizing using high-pressure steam to prepare first culture medium, mixing 8-12 g/l of chloride, 0.5-0.8 g/l of disodium hydrogen phosphate, 1.5-2 g/l of magnesium, 1.5-2 g/l of sodium chloride, 45-60 g/l of sodium bicarbonate, 15-20 g/l of yeast extract, 1.2-2 ml/l of ethanol, and 15-20 g/l of agar with 1000 ml of distilled water, sterilizing at high-pressure steam, adjusting pH of the mixture to 7 using phosphoric acid to prepare second culture medium, mixing 8-15 g/l of glucose, 6-10 g/l of yeast extract, 5-8 g/l of calcium carbonate, and 15-20 g/l of agar with 1000ml of water, adjusting the pH of the mixture to 5.5-5.8, sterilizing using high-pressure steam to prepare third culture medium, mixing 10-15 g/l of peptone, 3-5 g/l of yeast extract, and 5-10 g/l of sodium chloride with 1000 ml of distilled water, adjusting the pH of the mixture to 7-7.2, sterilizing using high-pressure steam to prepare fourth culture medium, mixing and stirring 90-120 g/l of corn syrup, and 100-150 g/l of brown sugar with 1000 ml of water, mixing and stirring 20-35 kg of corn syrup, and 150-200 Kg of brown sugar with 1000l of water, sterilizing using high-pressure steam, inoculating the strain into first culture medium, culturing at 28-35 degrees C for 48-72 hours, inoculating the Pseudomonas fluorescens into the second culture medium, culturing at 25-28 degrees C for 48-72 hours, inoculating the Bacillus subtilis into the third culture medium, culturing at 30-40 degrees C for 48-72 hours, inoculating the Bacillus megaterium into the fourth culture medium, culturing at 28-32 degrees C for 48-72 hours, mixing the cultured liquid, and culturing at 45-50 degrees C for 60-72hours. The first strain comprises Candida utilis, Candida tropicalis, and Geotrichum candidum. The sterilizing step is carried out at pressure of 0.5-3 MPa for 5-20 minutes. The cultured liquid is stacked at a height of 1-1.5 m and width of 1.5-3 m.
