Oxyluciferin may be reduced to luciferin at cathodes, when an electric current is passed through the solution, or at cathodes formed by metal couples in solution, or at cathodes of oxidation-reduction cells of the NaCl - Pt - Pt - Na2S type. It is also reduced at those metal surfaces (Al, Mn, Zn, and Cd) which liberate nascent hydrogen from water, although no visible hydrogen gas separates from the surface. Molecular hydrogen does not reduce oxyluciferin even though very finely divided but will reduce oxyluciferin in contact with palladium. Palladium has no reducing action except in presence of hydrogen, and apparently acts as a catalyst by virtue of some power of converting molecular into atomic hydrogen. Conditions are described under which a continuous luminescence of luciferin can be obtained. This luminescence may be used as a test for atomic hydrogen. It is suggested that the steady luminescence of bacteria is due to continuous oxidation of luciferin to oxyluciferin and reduction of oxyluciferin to luciferin in different parts of the bacterial cell.
