The procedure for obtaining ergosterol that can be used for a preparation of vitamin d and deratization compounds is described. Further, also phospholipids can be obtained that can be used for a production of instant yeasts. This procedure is based on the extraction of sediment from autolysate with a following concentration of extract and a chilling of ergosterol from the solution of n-hexane. The procedure permits the utilization of other lipids; especially those of phospholipid fraction can be obtained by foaming from the acetone solution. The soluble fraction of autolysate can be utilized as yeast extract for food, microbial diagnostic and biotechnological applications.
