Engineering of a multifunctional hemicellulase
Biotechnology Letters, 2009To engineer a multifunctional xylan-degrading enzyme, a chimera was created by fusing the xylanase domain of the Clostridium thermocellum xylanase (xynZ) and a dual functional arabinofuranosidase/xylosidase (DeAFc; from a compost starter mixture) through a flexible peptide linker.

Wetstorage of Bagasse with Hemicellulase
Advanced Materials Research, 2012In this paper, the effect of hemicellulase treatment on the properties of bagasse and treatment liquor was investigated, and the chemical components of bagasse after optimized hemicellulase treatment were compared with those of wet-stored bagasse.

Hemicellulases in the bleaching of chemical pulps
1997Hemicellulase-aided bleaching is the first full-scale biotechnical application in the pulp and paper industry which truly exploits the unique specificity and safety of biocatalysts. Hemicellulases are used to modify the structure of xylan and glucomannan in pulp fibers in order to enhance the chemical delignification.

Characterization of hemicellulases from thermophilic fungi
Antonie van Leeuwenhoek, 2012The thermophilic fungi Thermomyces lanuginosus, Malbranchea cinnamomea, Myceliophthora fergusii and the thermotolerant Aspergillus terreus were cultivated on various carbon sources, and hemicellulolytic and cellulolytic enzyme profiles were evaluated. All fungi could grow on locust bean galactomannan (LBG), Solka floc, wheat bran and pectin, except T ...

Hemicellulases: Diversity and Applications
2018This chapter examines the general nature of plant hemicellulose and introduces the types, activities, and uses of hemicellulases in biomass conversion technologies. The complex structure of hemicelluloses has dictated an accordingly diverse array of hemicellulases.

Hemicellulases in Lignocellulose Biotechnology: Recent Patents
Recent Patents on Biotechnology, 2013Hemicelluloses comprise a major part of renewable plant biomass and therefore have received considerable attention in lignocellulose biotechnology. Hemicelluloses are a heterogeneous group of structural polysaccharides such as xylan, mannan and arabinan named after their major constituent monomeric sugar.

Cellulases, Hemicellulases, and Pectinases
2014The study of cellulases is important from the standpoint of microbial conversion of biomass to feeds and chemical feed stock. The complex structure of hemicelluloses has dictated a correspondingly diverse array of hemicellulases. The concentration (or actually dilution) of enzyme preparation required to effect this level of depolymerization is ...

Alkaline Active Hemicellulases
2019Xylan and mannan are the two most abundant hemicelluloses, and enzymes that modify these polysaccharides are prominent hemicellulases with immense biotechnological importance. Among these enzymes, xylanases and mannanases which play the vital role in the hydrolysis of xylan and mannan, respectively, attracted a great deal of interest.

Production of hemicellulases by Penicillium digitatum
Phytochemistry, 1970Abstract Penicillium digitatum grew sparsely on media containing hemicelluloses, but filtrates from these cultures had high macerating activity. They also contained xylanase and released only galactose, arabinose and xylose from a potato cell-wall preparation and from organge protopectin.

Separation and quantification of cellulases and hemicellulases by capillary electrophoresis
Analytical Biochemistry, 2003Cellulases and hemicellulases are two classes of enzymes produced by filamentous fungi and secreted into the cultivation medium. Both classes of enzymes consist of a subset of classes of which the fungi produce several enzymes with varying molecular mass and pI but similar enzymatic activities.
