Vitamin Effect On The Synthesis ??f Polyphenolic Substances By Basidiomycetes
Ð. Ð?. Veligodska, Ð?. V. Fedotov
We studied the influence of certain vitamins on the intensity of the synthesis of polyphenolic compounds and carotenoids by some Basidiomycetes strains, such as Laetiporus sulphureus Ls-08, Fomes fomentarius Ff-1201 and Fistulina hepatica Fh-18. The registration of accumulation of dry biomass and content of polyphenols and carotenoids in the mycelia and culture filtrate of strains that were cultivated on glucose-peptone substrates (GPS) with vitamins was performed. The vitamins A, E, C, B1, B12, and PP at the concentration of 0.005, 0.01 and 0.05 g/l were applied as modification of GPS. We founded the species effect on the synthesis of vitamins, polyphenols, and carotenoids. We suggested separate application of vitamins A, E, B1, and B12 at concentration of 0.01 g/ l to induce the synthesis of polyphenols and carotenoids. Results of the study will be used to develop a modification of GPS for the cultivation of strains of polyphenolic substances of basidiomycete origin.
