Abstract

A strain producing extracellular endo-type inulase was selected from Actinomycetes isolated from soil, and identified as Streptomyces sp. The maximum inulase production was obtained with medium containing inulin 1.0%, yeast extract 1.0%, (NH$_4$)$_2$HPO$_4$ 0.4%, NH$_4$H$_2$PO$_4$0.8%, KCl 0.05%, MgSO$_4$ㆍ7$H_2O$ 0.05%, FeSO$_4$ㆍ7$H_2O$ 0.001% at 96 hours culture in jar fermentor. The endo-type inulase was considered to be an inducible enzyme produced by inulin only.
