Comparative studies on the role of nitrogenous compounds in the growth and perithecial development of Chaetomium aureum.
Sodium nitrate is a suitable nitrogen source supporting growth and perithecial formation in Chaetomium aureum. 31 inorganic and organic nitrogen sources at a concentration of 0.033% were used at different incubating temperatures (25, 30 and 35 degrees C). The cultures were grown in Petri dishes, culture tubes and Erlenmeyer flasks. An incubating temperature of 30 degrees C was found most suitable for perithecial formation. In general, a nitrogen source in a solid medium could induce better perithecial production than in liquid media.
