Metabolism of acetylene by Rhodococcus A1

  • 85 Accesses

  • 39 Citations


A Rhodococcus sp. which is able to grow on acetylene and methylacetylene as well as on more common carbon compounds was isolated from soil. Growth of the organism, respiration of washed cells, excretion experiments and enzyme studies were consistent with the degradation of acetylene via acetaldehyde. Cell-free extracts of organisms grown on acetylene contained an acetylene hydratase at high levels. This enzyme was inhibited by oxygen but not by high concentrations of the reaction product acetaldehyde.
