Pseudomonas fluorescens NCIMB 11764 is able to utilise cyanide (both KCN and Ni(CN) 4 2− ) as a nitrogen source for growth. Under such conditions cyanide oxygenase activity is induced. When potassium cyanate (KOCN) is supplied as the sole nitrogen source for growth, cyanase activity is induced. It has been demonstrated that these two enzymic activities are physiologically distinct, and are not co‐induced under any of the growth conditions tested.
