  ABSTRACT: In agriculture, phytase is one of the most important monogastric animal sources of nutrient components because it effectively catalyzes the release of phosphate from phytate and phosphorylated compounds. In present work, Aspergillus niger strain (own collection) was used. Various physical and chemical factors have been known to affect the growth and the production of phytase. The effect of carbon and nitrogen sources, temperature and pH for extra cellular phytase production was investigated. Maximal phytase activity of Aspergillus niger was detected in media with 1.0% sucrose as a carbon source. Among the inorganic and organic nitrogen sources, ammonium nitrate in concentration of 0.5% was found to be a favorable nitrogen source for phytase production in Aspergillus niger. Optimum temperature and pH for phytase production by Aspergillus niger were 30°C and 5.5.
