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.

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.

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.

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 ...

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.

Industrial Applications of Cellulases and Hemicellulases
2018Cellulase and hemicellulase products have been developed and widely used in many industrial settings over the last several decades. These applications include textile, animal feed, bakery, brewing, pulp and paper, and biofuel sectors. This chapter illustrates the mechanisms and examples of these applications.

Evaluation of the Effects of Hemicellulases on the Bleachability of Sulphite Pulps
hfsg, 1995Sulphite pulps were prepared from spruce chips with four cooking methods, differing in cooking pH, the use of additives such as anthraquinone, and the cooking time and temperature. Considerable differences in carbohydrate composition, lignin content and yield of the pulps were observed.

Hemicellulases: Their Occurrence, Purification, Properties, and Mode of Action
1976Publisher Summary The terms “hemicellulases” or “hemicellulose-degrading enzymes” refer to those enzymes that specifically degrade only hemicelluloses, and do not include the glycosidases—which—in addition to their activity on glycosides of low molecular weight, are also frequently capable of hydrolyzing the short-chain or monosaccharide appendages ...
