| Popis: | Ganodermaspecies have been known all over the world as highly medicinal mushrooms. Antimicrobial activity of it is an attractive approach which raises the global interests from the scientific community. In this study, the antimicrobial assay of ethanol and methanol extracts ofGanodermawere prepared by using the dried mycelial powder obtained from five different liquid media; was performed against seven plant pathogenic fungiviz., Alternaria macrospora, Aspergilus niger, A. flavus, Colletotrichum falcatum, Fusarium oxysporum, Pestalotiopsis mangiferaeandPenicillium sp. and two plant pathogenic bacteriaXanthomonas oryzaeandRalstonia solanacearum. The extracts of mycelia obtained from Yeast Wine Media exhibited the highest inhibition percentage as compared to rest. At concentration 1000ppm, there was complete inhibition of mycelial growth forAlternaria macrospora, Aspergilus nigerandA. flavuswhile forFusarium oxysporumandPenicillum sp. complete inhibition was observed at 500ppm but forColletotrichum falcatumandPestalotiopsis mangiferae, more than 80% mycelial inhibition at concentration 1000ppm in both ethanol and methanol extracts. In the case ofXanthomonas oryzaeandRalstonia solanacearum, at concentration 1000ppm, methanol extract showed the highest inhibition zone (3.50mm, 3.75mm).Ganodermaexhibited antagonistic effect against plant pathogenic fungi could add to the interest of developingGanodermaas a successful bioagent in the near future. Antioxidant activities were evaluated by using DPPH radical scavenging assay and Metal chelating activity on ferrous ions. The DPPH radical scavenging effect was detected in methanol extract (Inhibition% = 27.312%) was higher than that of the ethanol extract (Inhibition% = 24.79%) and also Ferrous ion chelating ability of methanol extract (Inhibition% =22.27%) was higher than the ethanol extract (Inhibition% =12.55%). It is clearly indicated that both methanol and ethanol extract of theGanodermashow antioxidant properties andGanodermaextracts act as an effective antioxidant agents. |
