Actinomycete Nonomuraea sp. isolated from Indonesian soil is a new producer of inulin fructotransferase

An actinomycete that excretes inulin fructotransferase to the culture supernatant was able to produce di-d-fructofuranose 1,2′:2,3′ dianhydride (DFA III) from inulin, with the greatest rate of enzyme activity at 65°C and at a pH of 5.5. Through chemotaxonomic and 16S rRNA gene analysis, this strain was identified as genus Nonomuraea in the Streptosporangiaceae family. This is the first report of an inulin fructotransferase producer in this family.
