METHOD FOR PRODUCING ORGANIC PIGMENT FOR COLORING POLYMERIC MATERIALS Russian patent published in 2018 - IPC C12N1/14 C09B61/00 C12R1/645 

FIELD: biotechnology.

SUBSTANCE: method for producing organic pigment for coloring polymeric materials involves growing strain of pigment-containing fungus Hypomyces odoratus VKPM F-242 on a nutrient medium containing boiled wheat or oat, wheat or rye bran, birch sawdust, ground corn cob, macro and microelements and tap water at a predetermined ratio of the components, under conditions of solid phase cultivation at a temperature of 22-24°C for 7-10 days and the pH of the medium is 6.0-6.2. Resulting biomass of mycelium is treated with petroleum and methyl tert-butyl ether at a volume ratio of mycelium and solvent of 1:6, filtered to obtain extract.

EFFECT: invention allows to increase yield of the target product and expand the spectrum of colors of organic pigment.
