Cellulase »Onozuka« from Trichoderma viride 1 U/mg
Special quality for ELOS analysis by VDLUFA
CAS [9012-54-8]
A multi-component enzyme system (1). Although the preparation has high cellulase activity, it still contains hemicellulases, and it degrades mannans, xylans, galactomannans, pectins and other polysaccharides. Recommended quality for ELOS analysis by VDLUFA. Temperature optimum: 40 - 50 °C pH-optimum: pH 4 - 5
Unit definition: 1 U catalyzes the liberation of 1 µmole glucose from sodium carboxymethyl cellulose per minute at 40 °C, pH 4.5; glucose determined with alkaline copper reagent (2).
Extraneous activities: α-amylase ca. 0.8 U, pectinase ca. 0.4 U, protease ca. 0.01 DMC-U, hemicellulase ca. 1 U/mg (1 U catalyzes the liberation of 1 µmole reducing groups from xylan per hour at 37 °C, pH 5.5, calculated as xylose).
