Amylolytic Isoenzymes of Thermoactinomyces vulgaris¹

^a Department of Bacteriology, Iowa State University, Ames, Iowa 50010

ABSTRACT

Thermoactinomyces vulgaris strain 5 produced two electrophoretically different -amylases. Precipitation with ammonium sulfate and acetone did not alter the electrophoretic mobilities of either amylase isoenzyme. Patterns of the hydrolysis products of amylose by the two amylase isoenzymes were essentially identical.
