摘要： A drilling or oil and gas well clean up and/or fracturing method comprises providing at least one polymer-degrading enzyme comprising a polypeptide of SEQ ID NO:15, which is added to a drilling fluid used during an oil and gas well drilling operation, or to a fluid used for an oil and gas well clean up and/or fracturing operation. Combined with a second enzyme comprising a polypeptide of SEQ ID NO: 2, the enzyme comprising a polypeptide of SEQ ID NO 15 can be used to degrade a xanthan, a guar, a hydroxyalkyl guar, a carboxyalkyl guar, a guar gum, a guar gum powder, a lignified coat of guar seeds or a solidified guar gum.

摘要： The invention relates to polypeptides having glucanase, eg endoglucanase, mannanase, xylanase activity or a combination of these activities, and polynucleotides encoding them. In one aspect, the glucanase activity is an endoglucanase activity (eg, endo-1,4-beta-D-glucan 4-glucano hydrolase activity) and comprises hydrolysis of 1,4-beta-D-glycosidic linkages in cellulose, cellulose derivatives (eg carboxy methyl cellulose and hydroxy ethyl cellulose) lichenin, beta-1,4-bonds in mixed beta-1,3-glucans, such as cereal beta-D-glucans or xyloglucans and other plant material containing cellulosic parts. In addition, methods of designing new enzymes and methods of use thereof are also provided. In alternative aspects, the new glucanases eg, endoglucanases, mannanases, xylanases have increased activity and stability at increased pH and temperature.
