Studies on physiological and nutritional requirements for growth and biomass of P. djamor

Abstract

The present investigation was carried out to find out the best suited physiological and nutritional requirement for growth and biomass of P. djamor. Among the studied different media, Potato Dextrose Agar Medium Potato Dextrose Agar medium, Temperature 26oC, pH 7 and Relative humidity 100 were found most suitable for growth and biomass of P. djamor. In different light wavelength red light was found more inducive for mycelial growth. In the midst of c different Carbon observed in sources sorbitol, mannitol and sucrose substituted carbon sourced were found most appropriate to enhance the growth and biomass of P. djamor than other sources of carbon. Similarly, different nitrogen sources were evaluated, among them PDA (Control) was superior for growth and biomass but at par with Ammonium sulphate and L. arginine while significantly least was observed in barium nitrate amended medium.
