Notes:
A dried proteolytic enzyme preparation “Thermitase” is produced of the cultural solution of Thermoactinomyces vulgaris. The procedure comprises concentration, sedimentation, ethanol and sodiumsulfate precipitation and drying in laboratorial and semitechnical scale.The elimination of rape seed oil which impairs the salt sedimentation was specially taken into account. A certain sedimentation procedure using caoline or a aqueous solution of CaCl2 and Na2HPO4 or filtration was elaborated to eliminate the lipid components in the concentrated solution.The method is convenient to get good yields of the thermostable protease.
