The present invention relates to a method and apparatus for recovery of lipids from microbial biomass. The method comprises providing wet microbial biomass to thermal pretreatment of at least 100 ° C in a pressure vessel, subjecting the thermally pretreated microbial biomass to extraction using a liquid hydrocarbon as an extractant, and subsequently, recovering a product containing lipids. La présente invention concerne un procédé et un appareil pour l'extraction de lipides à partir d'une biomasse microbienne. Le procédé consiste à soumettre une biomasse microbienne humide à un prétraitement thermique d'au moins 100°C dans une cuve sous pression, puis à soumettre la biomasse prétraitée thermiquement à une extraction en utilisant un hydrocarbure liquide en tant qu'agent d'extraction, et subséquemment, à extraire un produit contenant des lipides.
