CELLULASE HYDROLYSIS OF COTTON CELLULOSE - THE EFFECTS OF MECHANICAL ACTION, ENZYME CONCENTRATION AND DYED SUBSTRATES

Experiments with dyed and undyed cotton, using different cellulase con centration and with or with out mechanical action showed a high effect of those factors. The process with mechanical action have a higher we ight-loss. Dyed cotton with vat and sulfur dyes have almost the saute weight-loss than undyed cotton, but on reactive dyed cotton the cellul ase hydrolysis is shorter. It was also verified a decrease of hydrolys is extent with an increase of the reactive dye concentration on the co tton substrate. Some synergism due to the enzyme concentration was app arently observed on the changes of the length of the leaving sugars.
