Biotechnology Letters Aims and scope Submit manuscript

Summary

The three fractions of inulase differing in isoelectric pH were isolated from a strain ofAspergillus niger by isoelectric focussing and characterized in their temperature stability. These fractions had distinguishable thermal stability. Among them, one fraction (pI 5.2) having main activity showed a high thermal stability comparable to that of the Novozyme 230 (Novo A/S, Denmark) at 60°C.
