Abstract: The present invention relates to a process for producing enzymes and single cell oil. The process comprises that microorganisms capable of producing both single cell oil and enzymes are cultivated under conditions suitable for single cell oil production and enzyme production in a single cell oil production process. A microorganism culture comprising single cell oil and enzymes is obtained and at least part of the microorganism culture, of the supernatant and/or microorganism cells separated from the microorganism culture, of protein fraction enriched from the supernatant, and/or of protein fraction obtained from the cells is used as an enzyme preparation or as a source of enzymes. Single cell oil is recovered from the microorganism cells and used as biofuel, component of biofuel or as a starting material for biofuel production. Enzymes produced according to the process are used in the same or in another industrial process.

Abstract: A method for recovering lipids from microbial biomass, the method including providing wet microbial biomass which contains lipids to extraction without disrupting the biomass cell walls, and subsequently, extracting the 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 the lipids in the cells are contacted with the extractant. Subsequently the extracted lipids are recovered from or with the extractant.

Abstract: The present invention relates to a method for purification of lipid material originating from biological material. In the method the lipid material comprising acylglycerols and phosphorus impurities and at least one added nonpolar solvent and at least one added polar solvent is provided into a reaction zone whereby at least a two phase system comprising a nonpolar phase and a polar phase is formed. The phase system is heated in the closed reaction zone under mixing at a temperature from 150° C. to 300° C. and at a pressure wherein said solvents are in subcritical state, preferably of below 100 bar, dependent on the vapor pressure of the selected solvents, until the phosphorus impurity is removed from the polar phase. Subsequently, the nonpolar phase including the purified oil comprising acylglycerols is separated and recovered from said phase system.
