| 英文摘要 | The use of microorganisms to solubilize elemental phosphorus from insoluble rock phosphate is a promising method to greatly reduce not only environmental pollution but also production costs. phosphate-solubilizing microorganisms were isolated from soils in china, and a fungus strain (psm11-5) from a soil sample from an alum mine, with the highest phosphate solubilization potential, was selected and identified as a penicillium sp. strain psm11-5 could grow in buffered medium with ph values between 3.0 and 8.0 and showed phosphate solubilizing activity at ph values from 5.0 to 8.0. it also exhibited a degree of tolerance to the heavy metal ions, cd(2+), co(2+), and cr(6+). psm11-5 could rapidly solubilize tricalcium phosphate, and a high phosphate-solubilizing efficiency of 98% was achieved in an optimized medium. the strain could solubilize rock phosphate and aluminum phosphate with a solubilizing efficiency of approximately 74.5%, but did not solubilize iron phosphate. solubilization of phosphate depended on acidification. analysis of psm11-5 culture supernatants by capillary electrophoresis showed that tricalcium phosphate was solubilized to po(4)(3-) and ca(2+), and that the organic acid produced by the fungus was mainly gluconic acid at approximately ca. 13 g l(-1). in addition, psm11-5 produced ca. 830 mg l(-1) of citric acid when it was used to solubilize rock phosphate. these excellent properties of strain psm11-5 suggest that the fungus has potential for agricultural and industrial utilization. |
