Production of isoamylase by Escherichia intermedia.
A culture of a coliform bacteria isolated from soil produced isoamylase when grown in peptone-maltose-salts broth. The enzyme preparation was partially purified. Its similarity with isoamylase produced by Aerobacter aerogenes was established by studying its action upon various polysaccharides. A study of the organism producing isoamylase showed that it differed from A. aerogenes in some of its physiological properties. This organism was identified as Escherichia intermedia from morphological and cultural characteristics.
