The invention relates to a method for the purification ofnMicroorganisms, in particular a method for the removal ofnSolvent residues from microorganisms. A by breeding ofnMicroorganism-derived microorganism material is used after then'Solvent extraction subjected to a gentle treatment,nby at temperatures of 10 to 50 ° C, preferably 15nup to 30 ° C in a weight ratio between 10: 1 and 1; 5 withnpure or aqueous alcohol containing small amounts of hydrocarbonsnin the liquefied gas and gasoline boiling range, intimatelyncontacted and then at temperatures of 50 to 130 ° C,npreferably 80 to 120 ° C is dried slowly.nIf necessary, depending on the composition of the alcoholicn-v phase before thermal treatment, excess amounts ofnalcoholic phase of the microorganism material mechanically, e.g.nby centrifugation or filtration, separated. |
