Abstract
In present study the effect of carbon sources, glucose, sucrose, lactose, maltose, fructose, xylose and nitrogen sources such as ammonium sulfate, ammonium phosphate, ammonium nitrate, potassium nitrate, yeast extract, peptone on the phytase production has been studied. Maximal phytase activity of Aspergillus niger was detected in media with 1.0% sucrose as a carbon source. All other monosaccharides and disaccharides used had less effect on phytase production. 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
