Abstract excerpt
The effect of temperature, aeration and various foam suppressors on the growth of a mutant of Aspergillus terricola H-20 and on its production of proteolytic enzymes was studied. A high level of the proteolytic activity (12-15 PU/ml) was found at 28-30 degree C in conditions of aeration with the rate of oxygen dissolution being 0.38-0.86 g of oxygen per litre per hour. Synthesis of the enzyme was inhibited by a...
