Obtaining new cultures of microorganisms that produces cellulases and xylanases from the sugarcane bagasse
Background The international energetic system strongly depends on fossil fuels, which causes negative effects in the environment, such as the global warming. Biofuels appear as an environmental and economic alternative for the energetic industry because of their potential source of renewable energy. Several studies are based on sugarcane culture and its derivatives, as bagasse, the sugarcane re...
متن کاملXylanases, xylanase families and extremophilic xylanases.
Xylanases are hydrolytic enzymes which randomly cleave the beta 1,4 backbone of the complex plant cell wall polysaccharide xylan. Diverse forms of these enzymes exist, displaying varying folds, mechanisms of action, substrate specificities, hydrolytic activities (yields, rates and products) and physicochemical characteristics. Research has mainly focused on only two of the xylanase containing g...
متن کاملBacterial cellulases and xylanases
Although this review focusses primarily on bacterial cellulases and xylanases, there is considerable overlap in the molecular biology and biochemistry of prokaryotic and fungal forms of these enzymes. Therefore, fungal plant cell wall hydrolases are discussed where comparisons with the corresponding bacterial enzymes are important. Cellulases and xylanases encompass a collection of enzymes whos...
متن کاملBacterial xylanases: biology to biotechnology
In this review, a comprehensive discussion exclusively on bacterial xylanases; their gene organization; different factors and conditions affecting enzyme yield and activity; and their commercial application have been deliberated in the light of recent research findings and extensive information mining. Improved understanding of biological properties and genetics of bacterial xylanase will enabl...
متن کاملMolecular and biotechnological aspects of xylanases.
Hemicellulolytic microorganisms play a significant role in nature by recycling hemicellulose, one of the main components of plant polysaccharides. Xylanases (EC 3.2.1.8) catalyze the hydrolysis of xylan, the major constituent of hemicellulose. The use of these enzymes could greatly improve the overall economics of processing lignocellulosic materials for the generation of liquid fuels and chemi...
