Description générale

Manufactured by Yakult
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

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. Cellulase from Sigma has been used to degrade cello-oligosaccharides into glucose while investigating the biodegradability of bioabsorbable bacterial cellulose (BBC).

Actions biochimiques/physiologiques

Cellulases are produced by the intestinal flagellates of termites which are important for cellulose digestion of their host termites . Cellulases have different microbial origins and therefore different protein sequences .

Définition de l'unité

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).

Notes préparatoires

Dissolves in sterile deionized (DI) water in the presence of 0.15 polyhexamethylene biguanide (PHMB) at 3 mg/mL concentration.

Biofilm formation by Listeria monocytogenes is generally associated with its persistence in the food-processing environment. Serotype 1/2a strains make up more than 50% of the total isolates recovered from food and the environment, while serotype 4b strains are most often

Phototrophic biofilms are key to nutrient cycling in natural environments and bioremediation technologies, but few studies describe biofilm formation by pure (axenic) cultures of a phototrophic microbe. The cyanobacterium Synechocystis sp. strain PCC 6803 (here Synechocystis) is a model microorganism

The intestinal flagellates of termites produce cellulases that contribute to cellulose digestion of their host termites. However, 75% of all termite species do not harbour the cellulolytic flagellates; the endogenous cellulase secreted from the midgut tissue has been considered a

Cellulose biodegradation resulting from enzymolysis generally occurs in nature rather than in the human body because of the absence of cellulose degrading enzymes. In order to achieve in-vivo degradation in human body for in-vivo tissue regeneration applications, we developed a

Three employees from two different detergent companies were investigated for occupational asthma, using skin prick tests, serum specific IgE, and specific bronchial challenge. Two were challenged with lipase and one with cellulase. All three cases had immunological evidence of sensitisation
