- 5700 U endo-1,4-beta-glucanase/g.
Characterisation of the active substanceAlpha-galactosidase produced by Saccharomyces cerevisiae (CBS 615.94) Endo-1,4-beta-glucanase produced by Aspergillus niger (CBS 120604)Method of AnalysisDetermination:- colorimetric method measuring p-nitrophenol released by action of alpha-galactosidase from p-nitrophenyl-alpha-galactopyranoside substrate,
- colorimetric method measuring water soluble dye released by action of endo-1,4-beta-glucanase from azurine-crosslinked barley glucan substrate.
