Growth Response of Pleurotus spp. on Different Basal Media and Different pH Levels

Abstract

Five isolates of Pleurotus spp. viz. Pleurrtus florida. P. sajor-caju, P. eous, P. flabellatus, P. sp. were cultured on PDA media and maintained on PDA slants. All the isolated species were tested for biomass production in various media viz. Richard’s Broth, Asthana Hawker’s. Czapecks’ Dox, Potato Dextrose and Malt Extract  Broth media. The maximum biomass was recorded on Potato dextrose media in P. florida, (1.86 g). The minimum biomass was recorded on Asthana Hawker’s media in P.florida & P.eous (1.15g). All the isolated spp. were tested for the effect of pH variations. A pH range between 3 to 8 was recorded. The maximum biomass was recorded at 5.0 pH. The biomass gradually decreased in an acidic environment, similarly higher pH also did not favoured the growth as well as biomass.
