Summary A new inulin‐fermenting strain of Clostridium thermoautotrophicum was isolated through enrichment on dahlia tubers, and subsequent plating on agar media with undissolved inulin. Both the cell‐bound and cell‐free inulinase(s) functioned optimally at 60°C and atneutral pH. This new strain I1 is readily distinguished from the type strain of C. thermoautotrophicum with respect to fermentation products, substrate spectrum and optimum temperature for growth.
