Cellulases, Hemicellulases, and Pectinases: Applications in the Food and Beverage Industry

Food and Bioprocess Technology, 2021
Enzymes are present in all naturally occurring forms of life, including plants, animals, and microorganisms. Enzymes have been used in the food industry to transform a raw material into a main product, to modify the functional characteristics of a product, and/or to control or improve food processes.

Studies on the structure and function cellulases and hemicellulases.

Proceedings of the British Society of Animal Production (1972), 1993
Plant 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 ...

Hemicellulase Activity of Aerobic Fungal Cellulases

Holzforschung, 2000
SummaryCellulases 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.

Effects of Cellulases and Hemicellulase on the Alkaline Solubility of Dissolving Pulps

Holzforschung, 1998
Softwood 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, Hemicellulases, and Pectinases

2014
The 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 ...

Hydrolysis of different chain length xylooliogmers by cellulase and hemicellulase

Bioresource Technology, 2011
Commercial cellulase complexes produced by cellulolytic fungi contain enzyme activities that are capable of hydrolyzing non-cellulosic polysaccharides in biomass, primarily hemicellulose and pectins, in addition to cellulose. However, xylanase activities detected in most commercial enzyme preparations have been shown to be insufficient to completely ...

Cellulases and Hemicellulases for Biomass Degradation: An Introduction

2011
The 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.

Immobilization of Cellulase and Hemicellulases on Porous Glass Beads

Journal of ASTM International, 2010
Abstract Experiments on immobilization of cellulase complex (cellulase, Novozymes) and enzyme complex (cellulases and hemicellulases, Novozymes) were performed on porous Siran™ beads using covalent and non-covalent bonding methods. Free enzyme complex was used for hydrolyzing various pretreated biomass such as corn stover, distillers ...

Cellulase-hemicellulase complex of Phoma hibernica

1988
Publisher Summary The walls of plant cells contain a variety of polysaccharide polymers. These polymers are cross-linked and form compact structures. A number of substrate-specific hydrolases that degrade cellulose, hemicelluloses, and pectins have been described from fungi and bacteria.

Proteomics-based Compositional Analysis of Complex Cellulase–Hemicellulase Mixtures

Journal of Proteome Research, 2011
Efficient deconstruction of cellulosic biomass to fermentable sugars for fuel and chemical production is accomplished by a complex mixture of cellulases, hemicellulases, and accessory enzymes (e.g., >50 extracellular proteins). Cellulolytic enzyme mixtures, produced industrially mostly using fungi like Trichoderma reesei, are poorly characterized in ...
