Phosphorus is the vital element for the growth of plants. Bacillus megaterium strain P17 was isolated from yellow brown soil in Nanjing. Strain P17 could improve the solubility of insoluble phosphate. The solubilizing mechanism needs to be studied deeply. In this paper, the acid-production characteristics of Bacillus megaterium strain P17 were studied deeply. The volatile and nonvolatile organic acid produced by strain P17 was detected by GC. In addition, the acid-production characteristics of strain P17 was determined when strain P17 used different phosphorus sources.
