The influence of ammonium nitrate, ammonium sulphate, ammonium chloride, sodium nitrate, potassium nitrate and urea as nitrogen sources on the synthesis of fat by Aspergillus terreus, Aspergillus ochraceus, Cladosporium fulvum, Cladosporium herbarum and Penicillium gladioli has been studied. Sodium nitrate has proved to be the best source of nitrogen for production of fat by A. terreus, C. herbarum and C. fulvum where the highest yields obtained were of fat contents in the felt of 51.0, 29.2 and 23.5 %, respectively. In the case of A. ochraceus the highest yield of fat was obtained with urea as nitrogen source giving a fat content in the mycelium of 47.5%. The highest yield of fat by P. gladioli was obtained using ammonium nitrate, giving a fat content of 31.0%.
