Abstract
Abstract The production of alpha-1,6-glucosidase by the cultivation of a strain of Klebsiella pneumoniae ATCC 13883, Klebsiella rhinoscleromatis ATCC 13884, Klebsiella ozaenae ATCC 13885, Klebsiella edwardsii ATCC 13886 or Klebsiella rubiacearum ATCC 15574 on media consisting of carbon sources, nitrogen sources, inorganic salts and others under aerating and agitating conditions thereby resulting in accumulation of alpha-1,6glucosidase on the media and the separation of the alpha-1,6glucosidase from the media following the purification of the alpha-1,6-glucosidase.
