【Abstract】 The choose of phosphate solubilizing fungal strains with high efficiency in black soil and rock phosphate solubilization in liquid culture are studied in this paper. The results show that phosphate solubilizing fungi (PSF) are more efficient and more stable than phosphate solubilizing bacteria (PSB). Aspergillus spp ’P39’,’P37’ and Penicillium spp ’P66’,’P1’ have a strong ability of phosphate solubilization. Moreover there is no correlation between the ability of phosphate solubilization with pH and organic acid content in the culture filter. The differences among the phosphate solubilizaion of phosphate solubilizing fungi may be due to the variation and amount of organic acids produced by phosphate solubilizing fungi.更多还原
