ABSTRACT
Six different carbon (galactose, lactose, maltose, dextrose, malt extract, mannose) and nitrogen (sodium nitrate, ammonium sulphate, ammonium nitrate, peptone, urea, calcium ammonium nitrate) sources, malt extract and peptone, respectively were showed maximum mycelial growth of the fungus. The five trace elements were tested, each at 50 and 100 ppm concentrations, copper sulphate, ferrous sulphate, manganese sulphate and ammonium molybdate significantly increased the mycelial growth whereas, zinc sulphate was found lethal at 50 and 100 ppm concentration. Five vitamins were tested at 100 and 200 ppm concentrations, nicotinic acid at 100 ppm gave maximum mycelial growth of Hypsizygus ulmarius. In case of ascorbic acid, biotin, nicotinic acid and pyridoxine, the mycelial growth was inhibited at higher dose (200 ppm) as compared to lower dose (100 ppm) whereas, folic acid significantly increased the mycelial growth at both 100 and 200 ppm concentrations.
