A method for lipid extraction from biomass

摘要

The present invention relates to a method for recovering lipids from microbial biomass. The method comprises providing wet microbial biomass which contains lipids to extraction without disrupting the biomass cell walls, and subsequently, extracting said wet microbial biomass with a liquid extractant at elevated temperature of at least 170 ˚C and elevated pressure. The combination of the temperature and pressure is such that said lipids in said cells are contacted with said extractant. Subsequently the extracted lipids are recovered from or with said extractant.
