TECHNOLOGY FOCUS - BIOTECHNOLOGY - Preferred Components: The bacterial agent comprises Pseudomonas sp., Saccharomyces cerevisiae, Lactobacillus plantarum and Streptomyces microflavus at colony number ratio of 1.6:1.5:0.1:0.5. The bacterial agent is verotoxin antimicrobial agent. The compost material is domestic waste having granularity of 5-80 mm, water content of 50-60 wt.%, and carbon/nitrogen ratio of 23-26:1. The ratio (colony-forming unit/kg) of Pseudomonas sp., S. cerevisiae, L. plantarum, S. microflavus and compost material is 0.66:0.62:0.04:0.21:1. Preferred Method: High-temperature fermentation includes distributing compost in second fermentation bin of 20-25 (preferably 21.6) degrees C to form a stack having length of 27 m, width of 4 m and height of 3.5 m; blowing hot gas (preferably air of 40-55 degrees C produced by composting in first fermentation bin group including fermentation bin(s) different from second bin) into the second bin at 0.1 m3/minute/m3 stack while fermenting, and fermenting for 8 days until the temperature of compost is 65 degrees C, in which the gas exhausting amount is 0.1 m3/minute/m3 stack; and stopping blowing hot gas when the temperature of compost reaches 65 degrees C, and blowing air of 20-25 (preferably 21.6) degrees C at 0.1 m3/minute/m3 stack while fermenting to obtain primary composting product, in which the gas exhausting amount is 0.1 m3/minute/m3 stack. Continuous fermentation includes stacking the primary composting product into strip stacks having length of 27 m, width of 4 m and height of 2.5 m, and composting at 40-50 degrees C for 12 days while blowing air at 0.02 m3/minute/m3 primary composting product to obtain aged product; and sieving the aged product, collecting part with granularity of less than 25 mm, stacking part with granularity of less than or equal to 25 mm into strip stacks having length of 27 m, width of 4 m and height of 2, and composting at 20-30 degrees C for 12 days while blowing air at 0.0005 m3/minute/m3 undersieve material to obtain secondary composting product. The secondary composting product is sieved, and undersieve material with granularity of less than or equal to 12 mm, i.e. the fertilizer is collected. ACTIVITY - Fertilizer.
