Enzymatic stone-washing is performed either entirely without stones or sometimes by a combination of stones and enzymes. Cellulases are used to attack the surface of the cellulose fiber, but leave the interior intact. Denim garments are dyed with indigo blue, which stays on the surface of the yam. The cellulase pardy hydrolyzes the surface of the fiber, and the indigo blue is pardy removed. Either neutral-type cellulases acting at pH 6—8 or acid-type cellulases acting at pH 4—5 are used for these processes.

Foam fractionation is a promising technique for concentrating proteins because of its simplicity and low operating cost. One such protein that can be foamed is the enzyme cellulase. The use of inexpensively purified cellulase may be a key step in the economical production of ethanol from biomass. We conducted foam fractionation experiments at total reflux using the cellulase component P-glucosidase to study how continuous shear affects P-glu-cosidase in a foam such as a fermentation or foam fractionation process. The experiments were conducted at pH 2.4, 5.4, and 11.6 and airflow rates of 3,... 

The gut microbiota of termites synthesize and secrete the enzyme cellulase, which hydrolyzes the cellulose. 

Although some report that antibodies are able to penetrate cell walls fully, immunofluorescence micrographs of cell-wall protein localizations suggest that this is not the case (21). Antibody solutions infiltrated under vacuum into stem tissues do not appear to reach inner surfaces of the cell walls, whereas antibodies applied to cut surfaces of the stem clearly do (see Fig. 3 in ref 21). In order to facilitate the penetration of antibodies into plant cells, the cell walls need either to be opened or removed. This is most often accomplished by digestion with the enzymes cellulase and/or pectinase (22). 

It is well known that enzyme cellulases are the reason for the breakdown of cellulose by microorganisms. The search for highly efficient cellulase-produc-ing microbes and methods that can produce cellulase at a low cost are two key... 

The ability to digest cellulose is found only in microorganisms that possess the enzyme cellulase. Certain animal species (e.g., termites and cows) use such organisms in their digestive tracts to digest cellulose. The breakdown of the cellulose... 

Hnman beings lack the enzyme cellulase and are therefore nnable to break cellnlose down to individual glucose molecules. Although many fungi are able to break down cellulose to glucose, only a few types of bacteria have... 

The enzymes cellulase, mannanase, and aryl-/ -glucosidase showed no significant decrease in activity as determined in the presence of up to 60% of ethanediol. Xylanase, / -glucosidase, and mannosidase lost approximately half of their initial activity at this ethanediol concentration while xylosidase lost most of its activity. The inhibition caused by ethanediol was found to be reversible.

Carbohydrates. Cellulose is hydrolyzed to glucose by aeids and to cellobiose by its own specific enzyme cellulase. Alkali is not effective.
