Analysis of the influence of laser irradiation on the accumulation of biomass and polysaccharides pleurotus ostreatus (JACQ.) Р. Kumm

Abstract

The aim of the study was to investigate the effect of laser irradiation of mycelium on the amount of biomass and synthesis of P. ostreatus polysaccharides. Materials and methods. For the study, 6 strains of P. ostreatus from the Collection of cultures of basidiomycetes of the Department of Botany and Ecology of Vasyl Stus DonNU were used. A device consisting of LED lasers was used for laser irradiation of vegetative mycelium: BRP -3010-5, with red spectrum radiation with a wavelength of 635 nm; BBP -3010-5 with blue spectrum radiation with a wavelength of 405 nm and BGP -3010-5 with green spectrum radiation with a wavelength of 532 nm. The level of biomass accumulation was determined by weight. The polysaccharide content was determined by the phenol-sulfur method.
