title: Complete stabilization of water-soluble hydrogenase from Rhodospirillum rubrum under air atmosphere with a high concentration of chloride ions.
abstract: Hydrogenase was easily solubilized from light-grown cells of R. rubrum with 10 mM Na ethylenediaminetetraacetate. The enzyme thus obtained was so stable that loss of its activity was undetectable during storage at room temperature for 6 months under air atmosphere, provided that NaCl, KCl or CsCl was present at greater than or equal to 0.7 M.
