The 102 strains which can produce hydrolyzed circles were obtained using alternative medium containing phytate - calcium. after being isolated and purified, these strains were inoculated into fermented medium, shaking in 28 c at 220r / min for 5 days, then their enzymatic activities were determined by ammonium molybdate - phosphate colorimertry under the condition of 37 cand ph2. 5. the result showed there were 24 strains with higher enzymatic activities among the 102 strains, after the rescreening, 7 strains were gained with enzymatic activities beyond 15u / ml and stable ability of producing acidic phytase, of which, enzymatic activity of the strain 14 was the highest, reaching 53. 86u / ml, and it was preliminarilly identified as aspergillus. niger, then numbered as aspergillus. niger 14
