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

Three species of the β-Proteobacterial genus Herbaspirillum are able to fix nitrogen in endophytic associations with such important agricultural crops as maize, rice, sorghum, sugar-cane and wheat. In addition, Herbaspirillum rubrisubalbicans causes the mottled-stripe disease in susceptible sugar-cane cultivars as
