ABSTRACT:
The invention relates to a process for preparing a protein concentrate having a low nucleic acid content starting from a microbial cell mass. By subjecting a suspension of the cell mass to a mechanical disintegration followed by an incubation in the presence of a salt at 30.degree.-70.degree. C and at a pH of 5-9 the nucleic acid contained in the mass is degraded, the degradation products being separated from the protein and a protein concentrate being obtained. The invention also relates to the protein concentrate thus obtained.
