Abstract
The action of Bacillus macerans upon starch solutions has led to the isolation of crystalline dextrins by F. Schardinger (1). They are chemically homogenous and react readily with iodine to form both brown and blue colored complexes analogous to the starch-iodine complex. The Schardinger dextrins have been shown to be cyclic (2) and made up entirely of glucose residues bonded by a- 1, 4 - glucosidic linkages as in amylose. One of these, cyclohexaamylose (Schardinger's a- dextrin), containing as the name implies, six glucose units, reacts with iodide-free iodine in aqueous solution to form a stable crystalline complex. X-ray investigations have been carried out upon this complex to obtain evidence concerning the structural configuration of a compound closely analogous to the amylose-iodine complex.
