dc.description.abstract | The formation and location of endo-1,4-beta-glucanases and beta-glucosidases were studied in cultures of Cellulomonas uda grown on microcrystalline cellulose, carboxymethyl cellulose, printed newspaper, and some mono- or disaccharides. Endo-1,4-Glucanases were found to be extracellular, but a very small amount of cell-bound endo-1,4-beta-glucanase was considered to be the basal endoglucanase level of the cells. The formation of extracellular endo-1,4-beta-glucanases was induced by cellobiose and repressed by glucose. Extracellular endoglucanase activity was inhibited by cellobiose but not by glucose. beta-Glucosidases, on the other hand, were formed constitutively and found to be cell bound. beta-Glucosidase activity was inhibited noncompetitively by glucose. Some characteristics such as the optimal pH for and the thermostability of the endoglucanases and beta-glucosidases and the end products of cellulose degradation were determined. | |
