Process for producing enzymes

摘要

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.
