MICROBIAL CONVERSION OF METHANE Russian patent published in 2018 - IPC C12P7/64 C12P13/04 C12P1/00 C12M1/04 C12M1/40 

FIELD: biochemistry.

SUBSTANCE: group of inventions relates to biochemistry. Method is proposed for obtaining a lipid product by microbial conversion of a gaseous substrate (variants). In one variant, the method comprises providing a gaseous substrate in a culture containing one methanotrophic microorganism in a liquid nutrient medium of a bioreactor, microbially converting under fermentation conditions the gaseous substrate into a lipid product in the cell membrane of a methanotrophic microorganism and isolation of a lipid product from the cell membrane of a methanotrophic microorganism. Moreover, the gaseous substrate contains CH₄ and O₂ in the O₂:CH₄ from 5:1 to 0.9:1. In another variant, the method comprises feeding the substrate to a bioreactor containing a liquid nutrient medium and a single methanotrophic microorganism culture, microbiological transformation of the substrate to produce a lipid product and isolation of the lipid product from the cell membrane of the microorganism. And the substrate contains O₂ and one compound from CH₄, CH₃OH or a combination thereof.

EFFECT: inventions provide for the production of lipids from methane-containing gaseous substrates, as well as a reduction in the release of methane into the atmosphere.
