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 and Enzymes for Alternative Energy Research.
Application
Cellulase from Sigma has been used to degrade cello-oligosaccharides into glucose; to study the biodegradability of bioabsorbable bacterial cellulose (BBC) material.
Cellulase from Trichoderma reesei has been used in a study to assess the differential regulation of the cellulase transcription factors XYR1, ACE2, and ACE. Cellulase from Trichoderma reesei has also been used in a study to investigate the liquefaction of hydrothermally pretreated wheat straw at high-solids content.
Biochem/physiol Actions
Cellulases are enzymes that hydrolyze cellulose to glucose. Cellulase is used to study the development of occupational asthma in the detergent, pharmaceutical, baking, and enzyme production industries. Cellulase is added to detergents to improve cleansing properties. It is also applied in the biodegradation of paper products such as foolscap paper, filter paper, newspaper and office paper as well as microcrystalline cellulose.
Unit Definition
One unit will liberate 1.0 μmole of glucose from cellulose in one hr at pH 5.0 at 37 °C (2 hr incubation time).
Preparation Note
Dissolves in sterile deionized (DI) water in the presence of 0.15% polyhexamethylene biguanide (PHMB) at 5 mg/mL concentration.

Enzymatic liquefaction was studied by measuring continuously the flowability change of high-solids lignocellulose substrates using a real time viscometric method. Hydrolysis experiments of hydrothermally pretreated wheat straw were carried out with purified enzymes from Trichoderma reesei; Cel7A, Cel6A, Cel7B, Cel5A

Environmental issues such as the depletion of non-renewable energy resources and pollution are topical. The extent of solid waste production is of global concern and development of its bioenergy potential can combine issues such as pollution control and bioproduct development

Due to its capacity to produce large amounts of cellulases, Trichoderma reesei is increasingly being investigated for second-generation biofuel production from lignocellulosic biomass. The induction mechanisms of T. reesei cellulases have been described recently, but the regulation of the genes

Rice false smut, caused by the fungal pathogen Villosiclava virens, is one of the most important rice diseases in the world. Previous studies reported that the pathogen has less number of cell wall-degraded genes and attacks dominantly rice stamen filaments

The screening of catalysts, substrates or conditions in the early stages of bioprocess development requires an enormous number of experiments and is a tedious, expensive and time-consuming task. Currently available screening systems can only be operated in batch or fed-batch
