Microbial transformations of 6- and 7-methoxyflavones in Aspergillus niger and Penicillium chermesinum cultures.
نویسندگان
چکیده
A detailed study of the biotransformation of 6- and 7-methoxyflavones by four fungal strains (Aspergillus niger strains MB, KB, and SBP; Penicillium chermesinum 113) was carried out. Products of demethylation and also demethylation combined with hydroxylation at C-4' were identified. The biotransformation products were stronger antioxidants than the substrates.

Microbial transformations of 7-methoxyflavanone.
Microbial transformations of racemic 7-methoxyflavanone using strains of the genus Aspergillus (A. niger KB, A. ochraceus 456) and the strain Penicillium chermesinum 113 were described. The strain A. niger KB catalysed carbonyl group reduction, leading to (±)-2,4-cis-7-methoxyflavan-4-ol. Biotransformation with the help of A. ochraceus 456 gave two products: (+)-2,4-trans-7-methoxyflavan-4-ol a...

MS liquid medium supplemented with 3 mg/l NAA and 1 mg/l BAP with pH 5.7 was used for suspension cultures. Suspension cultures subjected to biotic elicitors Aspergillus niger, Fusarium oxysporium, Rhizopus oryzae and Penicillium notatum induced increase in forskolin content. Among all the elicitors tried Aspergillus niger proved to be best elicitor at 5% CF which was 6 times higher than the con...
