processo para a extração de lipídios de uma carga de alimentação microbiana

摘要

The present invention provides a process for the extraction of lipids from microbial lipid-containing feedstock, comprising the steps of (a) subjecting the microbial lipid-containing feedstock to a treatment to release the lipids thereby producing a mixture; (b) subjecting the mixture obtained in (a) to a filtration in the presence of a first extraction solvent on a filter, wherein organic matter soluble in an extraction solvent and an aqueous mixture are removed as filtrate from a retentate comprising non-soluble matter; (c) separating the filtrate obtained from the filter into an organic and aqueous phase; and (d) subjecting the organic phase to a distillation treatment to separate solvent and an organic residue comprising extracted lipids.
