摘要：
Extracellular phytase produced by Aspergillus sp. 5990 showed a 5-fold higher activity in liquid culture when compared with cultures of Aspergillus ficuum NRRL 3135. The optimum fermentation conditions were determined to be 35 °C, neutral pH, and 4 days incubation. The phytase had a higher optimum temperature for its activity than the commercial enzyme, Natuphos, from Aspergillus ficuum NRRL 3135.
