Abstract

Photoproduction of hydrogen and substrate conversion efficiency by resting cells of a photosynthetic purple non-sulfur bacterium Rhodobacter sphaeroides O.U. 001 varied with the gas phase of the assay. Both exogenous and endogenous substrates could support photoproduction of hydrogen by this organism. Substrate conversion efficiency of more than 100% was observed when Ar, Ar + 10% H2 and Ar + 10% N2 + 10% H2 were gas phases. This excess substrate conversion efficiency is attributed to hydrogen production from endogenous substrates. Dinitrogen (100%) and air in the gas phase totally inhibited hydrogen production. Hydrogen production was maximum in the presence of 10% H2 in the gas phase. However, 100% H2 atmosphere inhibited hydrogen production partially.
