Production by Aspergillus awamori of homologous oligosaccharides, each with an uneven number of glucosyl units and a reducing terminal (alpha , 1 leads to 4) linkage.
Homologous oligosaccharides with degrees of polymerization of 7 to 15 have been isolated from the nigeran-protein complex of Aspergillus awamori Nakazawa (QM873). Each contains an uneven number of glucose units, differs from its nearest homolog by two residues, and contains the sequence Glc(alpha , 1 leads to 3)Glc- (alpha , 1 leads to 4)Glc at its reducing terminus.
