Summary: A Gram-positive, aerobic, endospore-forming bacterium was isolated by an enrichment technique for the ability to degrade cyanide and was identified as a strain. The bacterium rapidly degraded 100 mg I of free cyanide in the absence of added inorganic and organic substances. The ability to degrade cyanide was linked to the growth phase and was not exhibited before late exponential/early stationary phase. Cyanide-degrading activity could not be induced before this time by the addition of 20 mg cyanide I. Production of the cyanide-degrading activity required 0.01 mg Mn I and did not occur at Mn concentrations below 0.002 mg I. Cyanide-degrading activity was intracellular and cell-free extracts rapidly degraded cyanide.
