摘要

METHOD OF RECOVERING PROTEIN OF LOW NUCLEIC ACID CONTENT FROM MICROORGANISMS Proteins of reduced nucleic acid content are obtained from micro-organisms by thermal treatment comprising heating an aqueous suspension of the micro-organism with the optional addition of a material having ribonuclease activity, at a pH value between 7 and 8.5 and at 63 to 67.degree.C, until the 5'-nucleotide content in the medium has reached the desired level, then briefly boiling the resulting mixture and separating the insoluble crude protein from the suspension.
