PROCESS FOR THE FERMENTATIVE PRODUCTION OF A LIPID FROM A STARTING MATERIAL, WHICH COMPRISES ALCOHOL, SOAPS AND/OR FATTY ACIDS, INVOLVING A STEP OF PRECIPITATING ALKALINE EARTH METAL SOAPS

摘要

The present invention concerns a process for forming a lipid or a mixture of lipids from a starting material, which comprises at least one alcohol and a soap or a soap precursor, the process comprising adding a metal-ion forming agent to the starting material, whereby a mixture is formed, which contains an insoluble phase and a liquid phase, separating the insoluble phase from the liquid phase, contacting the lipid-producing microorganism with the liquid phase on a culturing substrate, whereby the microorganism cells begin producing lipid, and collecting the lipids. The present invention also concerns a process for forming a lipid or a mixture of lipids from an alcohol-containing liquid phase, which comprises at least one alcohol.
