Antioxidant activity and total phenolic content of Volvariella volvacea and Schizophyllum commune mycelia cultured in indigenous liquid media

In the current work, we evaluated the different indigenous liquid culture media for mycelial production and antioxidant property based on radical scavenging activity and total phenolic content of Volvariella volvacea and Schizophyllum commune.In V. volvacea culture, the maximum mycelial biomass was significantly achieved in coconut water with 12.2 g, while S. commune efficiently grew on rice bran broth that produced the highest yield of 12.5 g.Similarly, the highest volume loss of spent was significantly recorded in these media for both mushrooms.Mycelia of V. volvacea grown in coconut water and S. commune in rice bran broth showed the most potent radical scavenging activity with 21.19% and 19.45%, respectively.The highest total phenolic content were found in rice bran broth with 23.19 mg AAE/g sample for V. volvaceamycelia and in coconut water with 25.52 mg AAE/g sample for S. commune mycelia.Therefore, mycelia these edible mushrooms may have potential as natural antioxidants which are affected by the liquid media.
