BIOCATALYST, METHOD OF ITS PREPARATION AND METHOD OF REETHERIFICATION OF VEGETABLE OILS USING THIS BIOCATALYST Russian patent published in 2015 - IPC C12N11/14 C12P19/02 B82B1/00 

FIELD: biotechnologies.

SUBSTANCE: biocatalyst for reetherification of vegetable oils is offered which contains as enzymatic active substation the partially destructed cells or cell lysates of the recombinant producer strain rE. coli/lip, carrier consisting of silicon dioxide and of nanostructured carbon, and maltodextrin or high molecular weight polysaccharide as the water-retaining agent. A biocatalyst is prepared by mixing of cells or cell lysates of the recombinant producer strain rE. coli/lip with the carrier and water-retaining agent of carbon nature with the subsequent drying and fractionating. The method of reetherification of vegetable oils is performed both in a periodic mode in a mixing reactor, and in a continuous mode in a flowing reactor with the fixed layer of a biocatalyst at the temperature 60-80°C.

EFFECT: high enzymatic activity of biocatalysts during reetherification of vegetable oils.
