By S. A. BARKER, E. J. BOURNE, and M. STACEY. nigeran," an intracellular polysaccharide of Aspergillus niger (strain 152), is a unique, essentially unbranched polyglucosan, in which about half of the glucosidic linkages are a-1: 4, and half a-1: 3; a small proportion of 1: 6-bonds also may be present. End-group assay revealed an average chain length of 300-350 anhydroglucose units. Most, if not all, of the a-1: 4-and a-1: 3-linkages are arranged alternately. The name" nigerose''is suggested for 3-O-or-~-glucopyranosyl-~-glucose.
