    摘要: A process for reducing the content of lipids and nucleic acids in a microbial cell mass to be used for food and feeding purposes, which comprises treating the cell mass with ammonia or ammonium hydroxide and with isopropanol or an organic solvent of the formulaR.sub.1 --(CH.sub.2).sub.n --OR.sub.2wherein either R.sub.1 and R.sub.2 are hydrogen, and n stands for one, two or three, or R.sub.1 is hydroxy, R.sub.2 is hydrogen, methyl or ethyl and n stands for two or three, and, after separation of the liquid, washing the residue with water, separating the aqueous phase and drying the residue.
