The aim of the study was to optimize the composition of lignocellulosic substrate based on peat and straw for growing fungi Pleurotus ostreatus. To achieve this goal, the following main tasks were set: analysis of the initial plant raw materials of peat and straw; study of the effect of an aqueous extract of peat on the growth of fungi Pleurotus ostreatus; study of the effect of the component composition of the substrate on the cultivation of oyster mushrooms.
Investigated the influence of the following relations medium : an aqueous extract of peat– 1 : 1; 1 : 2; 1 : 3; 1 : 4 and 1 : 10. The growth of fungi Pleurotus ostreatus was controlled by reducing the concentration of glucose and increasing the concentration of total protein in the culture medium. The kinetic characteristics of the growth of fungi Pleurotus ostreatus are determined from changes in the mass fractions of lignin, cellulose, easily and hardly hydrolyzed polysaccharides in substrates depending on the duration of cultivation of oyster mushrooms.
It is shown that the lignocarbon straw complex is more available for biodegradation than the lignocarbon peat complex. It was found that the addition of peat to the substrate together with straw creates optimal conditions for the growth of fungi Pleurotus ostreatus. To optimize the production of Pleurotus ostreatus, it is advisable to recommend a combined substrate with the following ratios of peat to breakage – 30 : 70% or 40 : 60%, respectively.
