Nutritional characteristics and physiological studies on the growth and development of Phlebiopsis gigantea

Abstract

Physiological studies pertaining to the effect of physical factors, carbon and nitrogen requirement of Phlebiopsis gigantea were conducted to know its behavior in vitro. These studies have revealed interesting results regarding its growth and reproduction behavior. The best medium for the optimum growth is glucose-peptone medium. The optimum temperature (28°C) and pH (5.0) is required for the optimum mycelial production of P. gigantea after 12 days of incubation. The fungus shows best growth in D(+) glucose and sodium nitrate whereas least growth is observed in sucrose and ammonium nitrate medium among various carbon and nitrogen sources, respectively, DL-threonine is found to be best among various organic nitrogen compounds for the growth of fungal mycelium.
