Production of mannanase by four hemicellulolytic microorganisms was studied. The highest mannanase activity was produced byBacillus subtilis. β-Mannosidase and α-galactosidase were not detected inB. subtilis culture filtrate. The hydrolysis of galactomannans was limited by the increasing degree of substitution of the substrate. No monomeric sugars were produced in the hydrolysis withB. subtilis culture filtrate.
