Abstract
Abstract Products which are soluble without opalescence even at pH 3 and which, because of their reproducible composition, are particularly well suited as a source of nitrogen for organisms are obtained by enzymatic degradation of uniform microbial cell aggregates, using endoproteases, and isolation of the protein fraction up to 2,000 Dalton, preferably from 400 to 1,500 Dalton.
