Hydrolysis of carbohydrate polymers represents one of the most important biotechnologies in the 21st century given the increasing demands for cellulose biomass-derived fuels. The key enzymes in this process (cellulases and hemicellulases) are produced by a wide variety of microorganisms [1] and their importance has prompted the development of various methods for high throughput screening and selection of microbial producers. Common screening techniques involve plate assays, where the target polymer substrate or a derivative has been incorporated intoa basal growth medium. Bacteria with extracellular cellulolytic activity are typically detected on agar media plate containing carboxymethylcellulose (CMC) or xylan as substrates. These substrates are polysaccharide organic compounds consisting of a linear chain of (1-4) linked d-glucose units and xylopyranose residues,respectively. Substrate hydrolysis can be revealed by clearing zones formed around the growing colonies after dye staining by Gram’s iodine [2–8] or Congo red
