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.

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.

Studies on the structure and function cellulases and hemicellulases.
Proceedings of the British Society of Animal Production (1972), 1993Plant structural polysaccharides provide a major source of nutrient for ruminant livestock. These carbohydrates are not degraded by mammalian-derived enzymes, but are hydrolysed by rumen microbial plant cell wall hydrolases. In view of the pivotal role of microbial cellulases and xylanases in ruminant nutrition, there has been considerable interest in ...

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.

Hemicellulase Activity of Aerobic Fungal Cellulases
Holzforschung, 2000SummaryCellulases isolated fromTrichoderma reeseiandPhanerochaete chrysosporiumwere screened for hemicellulolytic, pectinolytic and cellulolytic activity using locust bean mannan, birchwood xylan, citrus fruit pectin and carboxymethylated cellulose (CMC) as substrates.

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 ...

Hemicellulase production in Chrysosporium lucknowense C1
Journal of Cereal Science, 2009Filamentous fungi are widely used for enzyme production for the biofuel industry. The ascomycetous fungus Chrysosporium lucknowense C1 was isolated as a natural producer of neutral cellulases. It is at present an attractive alternative to well known fungi like Aspergillus sp. and Trichoderma reesei for protein production on a commercial scale.

Effects of Cellulases and Hemicellulase on the Alkaline Solubility of Dissolving Pulps
Holzforschung, 1998Softwood and hardwood dissolving pulps were treated with purified Trichoderma reesei endoglucanases, cellobiohydrolases and hemicellulases. Endoglucanase II decreased the viscosity and increased the alkaline solubility of the pulps most efficiently. The effect of EG II was not clearly improved by the action of hemicellulases or other cellulases.

Cellulases and Hemicellulases for Biomass Degradation: An Introduction
2011The development of second-generation biofuels will require a wide variety of lignocellulosic feedstocks that can be grown sustainably and processed cost-effectively in different geographical area. In nature bioconversion of lignocellulosic residues is initiated primarily by microorganisms such as fungi and bacteria.
