Abstract
The aim of this study was to select the conditions for submerged cultivation to obtain the highest yield of biomass. For the submerged cultivation various carbon and nitrogen sources were used as a replacement for glucose and peptone in the composition of the basic medium. Also, the growth of P. ostreatuswas studied on media with different initial pH values and at the different dissolution rates of oxygen. As a result, the pH value and aeration level of the cultivation medium providing the highest biomass yield were determined. Medium rye flour or dark wheat flour were selected as a source of carbon, soy flour was selected as the source of nitrogen. Submerged biomass of P. ostreatuscan be used for obtaining β-glucan-containing preparations used as BAS or functional supplements for the fortification of dairy and other food products.

Keywords: Pleurotus ostreatus, β-glucans, submerged cultivation, sources of carbon, sources of nitrogen, nutrient medium.
