General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency and waste prevention when used in cellulosic ethanol research. For more information see the article in biofiles.

Application

Cellulase from Trichoderma longibrachiatum has been used in a study to improve enzymatic saccharification. Cellulase from Trichoderma longibrachiatum has also been used in a study to investigate the effects of 2 exogenous pure cellulases on ruminal microbial growth and fermentation.
The enzyme has been used in the saccharification of biomass from energy cane during lignocellulosic ethanol production.[1] It has been used in the enzymatic hydrolysis of treated and untreated wheat straw to develop an eco-friendly, dry alkaline chemo-mechanical pretreatment of wheat straw. The purpose of this process is to save energy input, to decrease the environmental impact and to increase enzymatic hydrolysis without production of waste and liquid fraction.[2]

Biochem/physiol Actions

An acid cellulase with xylanase, pectinase, mannanase, xyloglucanase, laminarase, β-glucosidase, β-xylosidase, α-L-arabinofuranosidase, amylase, and protease activities

Unit Definition

One unit will liberate 1.0 μmole of glucose from cellulose in one hour at pH 5.0 at 37 °C (2 hr incubation time).

Fermentable sugars are important intermediate products in the conversion of lignocellulosic biomass to biofuels and other value-added bio-products. The main bottlenecks limiting the production of fermentable sugars from lignocellulosic biomass are the high cost and the low saccharification efficiency of
