Glycosylation of 6-methylflavone by the strain Isaria fumosorosea KCH J2.

ABSTRACT: Entomopathogenic fungi are known for their ability to carry out glycosylation of flavonoids, which usually results in the improvement of their stability and bioavailability. In this study we used a newly isolated strain of the entomopathogenic filamentous fungus Isaria fumosorosea KCH J2 as a biocatalyst. Our aim was to evaluate its ability to carry out the biotransformation of flavonoids and to obtain new flavonoid derivatives. The fungus was isolated from a spider's carcass and molecularly identified using analysis of the ITS1-ITS2 rDNA sequence. As a result of biotransformation of 6-methylflavone two new products were obtained: 6-methylflavone 8-O-β-D-(4"-O-methyl)-glucopyranoside and 6-methylflavone 4'-O-β-D-(4"-O-methyl)-glucopyranoside. Chemical structures of the products were determ
