The effect of initial pH on production mycelial biomass of Pholiota (Strophariaceae, Basidiomycota) species in liquid static culture

The article presents the effect of initial pH on production mycelial biomass of Pholiota species in a liquid static culture among seven Pholiota species from the IBK Mushroom Culture Collection of М.G. Kholodny Institute of Botany, National Academy of Sciences of Ukraine. New data on production mycelial biomass in a liquid static culture of Pholiota species are given. The growth characteristics of species depended on initial pH are shown. The most suitable pH values for each Pholiota species were find out, it ranged from 5,3 to 6,5. During cultivation, the initial pH of the nutrient media become lower. The studied Pholiota species differed not only in their ability to synthesize different amounts of biomass at optimal pH of the culture medium, but also demonstrate varying degrees of sensitivity to pH changes.
