Detection of Secondary Metabolite of Mycena pelianthina Growth in Various Liquid Medium

Abstract

Mushrooms which is mostly belong to the phylum Basidiomycota have been recognized as functional foods and a source for the nutraceuticals. Genus Mycena is one of mushrooms, which has been investigated for its secondary metabolites. Mycena pelianthina produces pelianthinarubins A, pelianthinarubins B, muscarin, and epimuscarin from alkaloid group. The purposes of this research were to determine the effects of composition of medium and incubation time on production of mycelial biomass of M. pelianthina in liquid medium and to know the group of secondary metabolite compounds produced. This research was done experimentally using a Factorial Completely Randomized Design consisted of 12 treatments and three replications. The first factor was medium type, which were Mushroom Complete Medium (MCM), Potato Dextrose Yeast Broth (PDYB), and Yeast Malt Extract Medium (YM). The second factor was the incubation time consisting of 15, 20, 25, and 30 days. The observed main parameters were the dry weight of mycelial biomass and the secondary metabolite groups. The dried weights of mycelia were analyzed using analysis of variance (ANOVA), continued with Duncan test at a 95% confidence level. The best growth of M. pelianthina mycelium was produced on PDYB medium at incubation time of 20 days with an average mycelial dry weight of 0.92 g/100 mL. M. pelianthina contained secondary metabolite compound groups of alkaloids, terpenoids, and flavonoids.
