Abstract
The activity of cobalt induced acrylonitrile hydratase was found to be 130% higher than the iron induced acrylonitrile hydratase in Arthrobaeter sp. IPCB-3. The activity of cobalt induced hydratase was not affected up to 6% (w/v) acrylonitrile and 25% (w/v) acrylamide. However, iron induced hydratase activity was significantly inhibited even at half the concentration of the above components. Such a higher tolerance for the substrate and the product makes the Arthrobacter sp. IPCB-3 a potential candidate for the commercial production of acrylamide.
