METHOD FOR CHEMICAL MODIFICATION OF MICROALGAE LIPIDS, METHOD OF PRODUCING SOAP AND SOAP CONTAINING FATTY ACID SALTS OF SAPONIFIED MICROALGAE LIPIDS Russian patent published in 2015 - IPC C12P7/64 C12N1/12 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to microbiology. The method for chemical modification of microalgae lipids includes culturing Prototheca microalgae to obtain a biomass containing at least 10% microalgae lipids with respect to the dry weight of cells and not more than 500 mcg/g dye inclusions and carrying out a chemical reaction, resulting in covalent modification of lipids. Culturing is carried out under heterotrophic conditions until the cells enter the lipid accumulation phase. The chemical reaction is selected from saponification, reesterification, interesterification, hydroxylation, cyclopropanation, epoxidation, hydroprocessing, deoxygenation, isomerisation, hydrogenation and hydrolysis. Also disclosed is a method of producing soap, which includes using Prototheca microalagae biomass, containing at least 5% microalgae lipids with respect to the dry weight of cells and not more than 500 mcg/g dye inclusions, and saponification of microalgae lipids. Also disclosed is soap which contains fatty acid salts.

EFFECT: group of inventions enables to obtain microalgae biomass with high content of lipids.
