NOVELTY - Preparing jelly-like mixed culture involves activating Bacillus subtilis and inoculating in seed broth I. The obtained seed broth I culture is inoculated in fermentation medium I at 33-37 degrees C under 1.33-1.88 ventilation volontaire maximale (vvm) for 26-36 hours to obtain cell concentration of 20-50 billion/ml. The fermentation medium I contains corn flour (40-60g/L), soybean powder (30-40g/L), magnesium sulfate (10-15g/L), glucose (8-10g/L) and dipotassium hydrogen phosphate (1-1.5g/L) at pH 7-7.5. Bacillus mucilaginosus is activated and inoculated in seed broth II.    USE - Method for preparing jelly-like mixed culture for preparing fertilizer (claimed).    ADVANTAGE - The method enables to prepare jelly-like mixed culture that reduces water activity and spores germinate rate, and improves shelf life and activity of bacteria.    DETAILED DESCRIPTION - Preparing jelly-like mixed culture involves activating Bacillus subtilis and inoculating in seed broth I. The obtained seed broth I culture is inoculated in fermentation medium I at 33-37 degrees C under 1.33-1.88 ventilation volontaire maximale (vvm) for 26-36 hours to obtain cell concentration of 20-50 billion/ml. The fermentation medium I contains corn flour (40-60g/L), soybean powder (30-40g/L), magnesium sulfate (10-15g/L), glucose (8-10g/L) and dipotassium hydrogen phosphate (1-1.5g/L) at pH 7-7.5. Bacillus mucilaginosus is activated and inoculated in seed broth II. The obtained seed broth II culture is inoculated in fermentation medium II at 30-33 degrees C under 1.60-2 vvm at 180-220 rotations per minute for 12-14 hours to obtain cell concentration of 10-20 billion/ml. The fermentation medium II contains sucrose or glucose (15-20g/L), dipotassium hydrogen phosphate (0.2-0.5g/L), magnesium sulfate (0.2-0.4g/L), sodium chloride (0.2-0.4g/L), ammonium sulfate (1-3g/L), calcium carbonate (3-5g/L) and yeast extract (1-2g/L) at pH 7-8. The obtained Bacillus subtilis and Bacillus mucilaginosus fermented cultures are mixed to obtain jelly-like mixed culture (40-60 vol.%).
