[beta-1,3-1,4-glucanase in spore-forming microorganisms. IV. Properties of some Bacillus-beta-glucan-hydrolases (author's transl)].

The beta-glucan-hydrolases produced by seven Bacillus species have been characterized with regard to some physicochemical properties. Ca-ions stabilize all tested glucanases. Optimum pH and optimum temperature were found to be different for the investigated enzymes. In the work presented here is given further characteristics of Bacillus-beta-glucan-hydrolases as pH-stability and temperature stability, sensibility on glucono-1,5-lactone, as well known inhibitor of carbohydrases, and electrophoretic mobility on cellulose acetate-sheets.
