ABSTRACT:
Disclosed is a novel non-reducing saccharide-forming enzyme. The enzyme can be obtained from the culture of microorganisms such as Rhizobium sp. M-11 (FERM BP 4130) and Arthrobacter sp. Q36 (FERM BP-4316), and is capable of forming non-reducing saccharides having a trehalose structure when allowed to act on reducing partial starch hydrolysates having a degree of polymerization of 3 or greater. Glucoamylase and .alpha.-glucosidase readily yield trehalose when allowed to act on the non-reducing saccharides. These non-reducing saccharides and trehalose are useful in food products, cosmetics and pharmaceuticals.
