Etude de L'Acétonitrilase D'une Souche de Brevidacterium

Abstract

The acetonitrilase from Brevibacterium R 312 has an activity between pH 5 and 10, with an optimum pH of 7, the optimum temperature is between 30°C and 35°C. It is a thermolabile enzyme and the temperature denaturation starts at 35°C. The Michaelis constant is near 2, 5.10^-2M. The enzyme is localized in the 180000g supernatant. It is an non adaptative enzyme.
