Cellulose is produced by plants and other photosynthetic organisms and is the most abundant renewable source of carbon on the planet. Efficient utilization of cellulosic biomass is a promising route in developing a society free from fossil-based energy and materials. The highly recalcitrant crystalline structure of cellulose is however still a significant bottleneck when it comes to enzymatic degradation into fermentable glucose, and thus new and better enzymes are highly desirable. In this project, the enzymes produced by certain cellulolytic soil bacteria are mapped through -omics techniques. The studied bacteria lack certain typical cellulose-degrading enzymes, and as such they are able to deconstruct cellulose crystals by a so far unknown mechanism, which might be utilized in bioenergy applications.
