TECHNOLOGY FOCUS - BIOLOGY - Preferred Process: The microorganism inoculant is prepared by: inoculating the strain with CGMCC No. 5090 into the bevel culture medium (A) in 30-38 degrees C culture box , standing under dark condition and culturing for 36 hours; washing inclined surface with sterile water to form a bacterial suspension; inoculating 1 unit of bacterial suspension to 20 units of the liquid culture medium (A) at 30-38 degrees C, cultivating with oxygen until the cell concentration goes to 108/ml; adding 5-10 times of the volume of a culture medium (B) into the bacterial suspension at 30-38 degrees C, culturing with oxygen until cell concentration goes to 108/ml; adding obtained bacterial suspension into 500-800 volumes of a culture medium (C) at 35-38 degrees C, culturing with oxygen until cell concentration goes to 108/ml; adding obtained bacterial suspension into 5-10 times volume of a culture medium (D) at 35-38 degrees C, cultivating with oxygen until cell concentration goes to 109/ml, stopping fermentation; then mixing with turf according to ratio of 1:2-10, granulating, drying, obtaining low temperature microorganism strain agent, where the culture medium (A) comprises 5 g/l of peptone, 5 g/l of sodium chloride, 5 g/l of beef extract, and 1.5-2% of agar, where the pH of the sewage is adjusted to 6.5-7.8 or the culture medium (A)does not contain agar, other components and contents are same as (A) , the PH of the sewage is adjusted to 6.5-7.8, the culture medium (B) comprises 5 g/l of starch , 0.2 g/l of sugar, 5 g/l of yeast juice, 5 g/l of peptone, 5 g/l of beef extract, 5 g/l of ammonium sulfate, 0.5 g/l of potassium dihydrogen phosphate, 0.2 g/l of magnesium sulfate and 5 g/l of sodium chloride, where the pH of the sewage is adjusted to 6.5-7.8, the culture medium (C) comprises 10 g/l of starch, 5 g/l of sucrose, 0.1 g/l of yeast diffusion juice, 0.5/g/l of peptone, 10 g/l of bean cake powder, 10 g/l of ammonium sulfate, 1 g/l of potassium dihydrogen phosphate and 0.5 g/l of sodium chloride, where the pH of the sewage is adjusted to 6.5-7.8, the culture medium (D) comprises 10 g/l of starch, 2.5 g/l of sucrose, 0.1 g/l of yeast diffusion juice, 0.5 g/l of peptone, 5 g/l of bean cake powder, 0.5 g/l of ammonium sulfate, 1 g/l of potassium dihydrogen phosphate and 0.5 g/l of sodium chloride, where the pH of the sewage is adjusted to 6.5-7.8. The microorganism inoculant is prepared by: inoculating the strain with CGMCC No. of 5090 into 1000 ml of culture medium comprising 10% of starch, 10% of bean cake powder, 0.2% of ammonium sulfate, 0.1% of dipotassium phosphate, 0.05% of iron chloride, 0.001% of calcium carbonate, 0.01% of yeast extract paste, pH of 7.2-7.4, shaking triangular flask at speed of 160 revolutions per minute at 30-38 degrees C for 16 hours, then inoculating to 200 l of seed fermenting tank according to 1% inoculating amount at 30-38 degrees C, culturing for 16 hours and then inoculating into 2000 l of fermentation tank according to 10% of inoculating amount, then at 30-38 degrees C, culturing for 20 hours, heating at temperature of 40-45 degrees C for 10 hours, after the 80% of spore fermentation is stopped, then mixing with grass according to ratio of 1: 2-10, granulating, drying at low-temperature, obtaining microorganism strain. Preferred Components: The fermentation liquid is mixed grass according to ratio of 1: 4. Preferred Components: The normal fertilizer is nitrogenous fertilizer, a potassium fertilizer and/or phosphate fertilizer and the organic carrier is chicken manure, crushed corn core and/or slag.
