Abstract
An improved process for the recovery of proteins from aqueous solutions of proteins, for example, proteases from fermenter solutions, by precipitation by means of salts and filtration, optionally with the use of common filtration aids, which is characterized in that a polyoxyethylene glycol having a molecular weight of 400 to 1,000, preferably 500 to 800, is added in an amount of from 0.5 to 3% by weight to the aqueous solution of proteins before said precipitation.
