Abstract

L'invention a pour objet un procédé de réduction de la teneur en lipides et en acides nucléiques de masses cellulaires microbiennes Suivant ce procédé, on traite la masse cellulaire avec de l'ammoniac ou de l'hydroxyde d'ammonium et un solvant organique de formule générale I :The invention relates to a method for reducing the content of lipids and nucleic acids in microbial cell masses. According to this method, the cell mass is treated with ammonia or ammonium hydroxide and an organic solvent of general formula I:
