In the present study, the bacterium Rhodopseudomonas palustris CGA009 has been Immobilized separately in an aqueous pool of the reverse micelles fabricated by various surfactants (AOT, CBAC and SDS) and apolar organic solvents (benzene and isooctane). All reverse micellar systems of bacterial Culture gave encouraging hydrogen production (rate as well as yield) compared to the aqueous system. An average of 50 fold increase in hydrogen production rate was observed in case of AOT/isooctane reverse micellar system as compared to the aqueous culture. CBAC/isooctane reverse micellar system is used for the first time for hydrogen production and is as promising as AOT/isooctane reverse micellar system. All these reverse micellar media were screened to reduce the inhibitory effect of NH4+ on hydrogen production. Studies of the effects of pH, temperature and light intensities on hydrogen production in reverse micelles show optimal hydrogen production at 37 degrees C temperature, 600 lx light intensity and 7 pH.
