To optimize the liquid fermentation medium and conditions for a phosphate-decomposing Bacillus strain YC4 isolated from aquaculture ponds, nutrient sources and major influencing factors were experimented under shake flasks to obtain their effects on the cell growth and spore formation and the growth curve of the strain was established. The optimal medium is determined to be composed of 10‰ of molasses, 5‰ of soybean protein powder, 5‰ of yeast extract, 5‰ of KH2PO4, 1.5‰ of MgSO4,15‰ of NaCl and 5‰ of corn steep liquor, and the optimal fermentation condition is 30℃ with initial medimn pH of 7.0
