Regulation Of The Synthesis Of Polyphenolic Substances By Some Basidiomycetes Strains

Abstract

O. V. Fedotov, A. K. Veligodska

The effect of specific carbon-containing compounds as additional components glucose-peptone medium (GPM), the intensity of the polyphenolic substances and carotenoids synthesis by some strains was investigated by surface cultivating basidiomycetes. The total content of polyphenolic substances set out in alcoholic extracts of the modified procedure by Folin-Chokalteu and in acetone carotenoids extracts of mycological material by spectrophotometric method and calculated by Vetshteyn formula. In GPM we used 13 carbonaceous components compounds belonging to mono-, oligo- and polysaccharides and carboxylic acids The effect of the 13 carbon-containing compounds on the accumulation of biomass, carotenoids and polyphenols Basidiomycetes strains L. sulphureus Ls-08, F. fomentarius Ff-1201 and F. hepatica Fh-18 was identified. For the purpose of inducing the synthesis of carotenoids by strains Ls-08 and Fh-18 may recommend changes in the standard GPS by fructose, and for strain Ff-1201 by sucrose. In order to induce synthesis of polyphenols strains Ff-1201 and Fh-18 to make appropriate standard GPS by mannose and for strain Ls-08 by sucrose.
