Production and properties of inulinase from Aspergillus niger

1994

Ongen-Baysal, G. | Sukan, S.S. | Vassilev, N.

A thermostable inulinase was identified in a strain of A. niger. The highest activity was observed at 50 degrees C (50 Uml-1) and 77% and 34% of this was retained at 60 degrees and 65 degrees C, respectively. pH stability, the effect of thermal stabilizers such as propylene glycol (10%) and sorbitol (10%) and effects of different cations were investigated. It was found that the activity was completely inhibited by Ag+ and Hg2+, while Na+ had an activator effect.
