ABSTRACT

Mycelial biomass production of mushrooms is now of considerable interest in order to elucidate their chemical compositions and biological activities. This present work demonstrated the production of mycelial biomass of Pleurotus djamor and Ganoderma lucidum using different indigenous liquid culture media. Corn grit produced the highest mycelial biomass and volume loss of culture spent of both P. djamor (6.12 g and 12.07 ml) and G. lucidum (9.10 g and 18.00 ml), respectively. Mycelia of P. djamor grown in corn grit recorded the highest radical scavenging activity of 73.29% and total phenolic content of 267.28 mg AAE/g sample. However, G. lucidum mycelia grown in coconut water showed the highest radical scavenging activity (77.33%) whereas mycelia in corn grit broth had the highest total phenolic content (402.75 mg AAE/ g sample). Collectively, the production of mycelial biomass and antioxidant activities of P. djamor and G. lucidum are dependent on the liquid culture media. Keywords: Anti oxidant properties, Pleurotus djamor and Ganoderma lucidum
