There is a major international effort to develop renewable alternatives to fossil fuels. One approach is to produce a liquid fuel by enzymatically hydrolyzing carbohydrate polymers in biomass to sugars and fermenting them to ethanol. Cellulose is the main polymer in biomass and cellulases can hydrolyze it to cellobiose, which can be converted to ...

A magnetic nanocomposite was prepared by entrapment of Fe3O4 nanoparticles into the cross-linked ionic liquid/epoxy type polymer. The resulting support was used for covalent immobilization of cellulase through the reaction with epoxy groups.

Abstract The involvement of cellulase (endo-b-l,4-glucanase, EC 3.2.1.4) in a number of different cell separation events which occur in higher plants has been well established. Besides their significance for the plant growth and differentiation, these events can be economically important since they also comprise softening of fleshy fruits and ...

CELLULASES classified as Cx attack soluble derivatives of cellulose, such as carboxymethylcellulose or hydroxyethylcellulose, and also substrates such as alkali or acid swollen cellulose. Highly ordered cellulose as in the cotton fibre is, however, not attacked.

Cellulase is an enzyme playing a crucial role in biotechnology industries ranging from textile to biofuel because of tremendous amount of cellulose produced in plant. In order to improve cellulase productivity, huge resource has been spent in search for good cellulases from microorganism in remote areas and in creation of ideal cellulase by engineering.

THERE are only a few reports of enzymes from higher plants which can hydrolyse cellulose or water-soluble cellulose derivatives. Several reports show that malt extracts are capable of hydrolysing water-soluble cellulose derivatives1,3,11 and dispersed cellulose fibres1,7.

Cellulose, cellulases and cellulosomes
Current Opinion in Structural Biology, 1998The structural complexity and rigidity of cellulosic substrates have given rise to a phenomenal diversity of degradative enzymes--the cellulases. Cellulolytic microorganisms produce a wide variety of different catalytic and noncatalytic enzyme modules, which form the cellulases and act synergistically on their substrate. In some microbes, several types

This study was designed to evaluate the effect of applying lactic acid bacteria (LAB, Lactobacillus plantarum LP) (0 and 1 × 106 cfu/g fresh matter (FM)) and cellulase (0, 30, 60 and 120 U/g FM) on the ensiling characteristics of N. cadamba leaves.

Deactivation of cellulases by phenols
Enzyme and Microbial Technology, 2011Pretreatment of lignocellulosic materials may result in the release of inhibitors and deactivators of cellulose enzyme hydrolysis. We report the identification of phenols with major inhibition and/or deactivation effect on enzymes used for conversion of cellulose to ethanol.

Visualizing cellulase activity
Biotechnology and Bioengineering, 2013AbstractCommercial exploitation of lignocellulose for biotechnological production of fuels and commodity chemicals requires efficient—usually enzymatic—saccharification of the highly recalcitrant insoluble substrate. A key characteristic of cellulose conversion is that the actual hydrolysis of the polysaccharide chains is intrinsically entangled with ...
