KLEBSILELLA OXYTOCA NO.19-1 AND PREPARATION OF ALPHA CYCLODEXTRIN USING KLEBSILELLA OXYTOCA NO. 19-1

摘要

The present invention relates to a new strain of Klebsiella oxytoca No. 19-1 separated from soil digesting starch and producing alpha -cyclodextrin with a very high selectivity and also to a process for producing alpha -cyclodextrin exclusively in high yield from starch by use of cyclomalto-dextrin glucanotransferase produced by the strain.
