ABSTRACT:
The present invention is directed to an exo-type hydrolase capable of hydrolyzing a fructan only every 3 or 4 sugar units from a terminal fructose thereof to produce predominantly inulotriose and/or inulotetrose. The enzyme is produced by Streptomyces sp. MCI 2423 (FERM BP-2678) and Aureobacterium sp. MCI 2494 (FERM BP-2679).
