Abstract
A novel cellulase was isolated from the thermoacidophilic bacterium Alicyclobacillus acidocaldarius ATCC27009 grown in medium containing carboxymethylcellulose. The enzyme is a glycosylated monomer of 56.2 kDa, relatively thermostable, with optimal pH and temperature of 4.0 and 65 °C, respectively. Enzymatic assays on several polysaccharides demonstrated that CelG was specific for carboxymethylcellulose.
