Abstract
Zgłoszenie dotyczy sposobu wytwarzania 4'-hydroksyflawonu o wzorze 2. Postępując zgodnie z wynalazkiem, w wyniku działania układu enzymatycznego zawartego w komórkach szczepu Beauveria bassiana KCh J1, następuje O-demetylacja. Uzyskany w ten sposób produkt wydziela się z wodnej kultury mikroorganizmu, znanym sposobem, przez ekstrakcję rozpuszczalnikiem organicznym niemieszającym się z wodą (octan etylu).The application relates to a process for the production of 4'-hydroxy flavone of the formula 2. In accordance with the invention, O-demethylation occurs as a result of the enzyme system contained in the cells of the Beauveria bassiana KCh J1 strain. The product obtained in this way is separated from the aqueous culture of the microorganism by a known method by extraction with a water-immiscible organic solvent (ethyl acetate).
