Alpha-glucosidases release terminal, 1,4- and to lesser extend, 1,6- linked -glucose residues of disaccharides, oligosaccharides, and aryl-glucosides. Among these, novel thermostable enzymes from hyperthermophiles and moderate termophiles have been investigated. The aim of this article is to demonstrate different sources of thermostable alpha-glucosidases, as well as properties and suitability of these enzymes for production of glucose at 90-100C, e.g., during one step process initiated by starch liquefaction using commercial alpha-amylase (Termamyl).
