Activity of the Aspergilli on Cellulose, Cellulose Derivatives, and Wool

Abstract
SUMMARY1. The isolates of any particular species of Aspergillus are alike in their ability to attack a particular substratum, such as cellulose or wool.2. Some species of Aspergillus can attack both autoclaved wool and cotton, some one but not the other, and still others can attack neither.3. Some species of Aspergillus are capable of degrading crude cotton duck but not the more pure cellulose of bleached cotton sheeting. These organisms are cellulolytic. Failure to grow on the cotton sheeting must be attributed to other causes.4. All members of the genus Aspergillus appear to be capable of hydrolyzing the 1,4 β-glucosidic linkages found in the cellulose chain.
