General description
Cellulase is a member of glycoside hydrolase family and is produced by a number of cellulolytic microbes.
Application
Cellulase from Aspergillus niger has been used:
- in the preparation of the standardized solution to determine absolute cellulase levels
- in phosphate-citric acid buffer for activity assay
- in non-starch polysaccharide degrading enzyme cocktail for in vitro hydrolysis of defatted rice bran and in the approach to improve the nutritive value of poultry feed
Biochem/physiol Actions
Cellulase from Aspergillus niger catalyzes the hydrolysis of endo-1,4-β-D-glycosidic linkages in cellulose, lichenin, barley glucan, and the cellooligosaccharides cellotriose to cellohexaose. It does not cleave cellobiose or p-nitrophenyl-β-D-glucoside. This enzyme will also cleave intact glycosaminoglycan from a core peptide by hydrolyzing the xylosyl serine linkage.
Other Notes
1 U corresponds to the amount of enzymes which liberates 1 μmol glucose from carboxymethylcellulose per minute at pH 5.0 and 37°C

Microplastic particles (MP) are efficiently retained in wastewater treatment plants and enriched in sewage sludge. For monitoring MP contents in wastewater systems, sewage sludge is thus well suited, but also requires an isolation of MP from the sludge matrix, as
