| Abstract: | In order to increase the yield of hydrogen production for hydrogen-producing microbe, the enhancement effect of nanometer- sized gold panicles on the activity of hydrogen-producing microbe was studied. The yields of hydrogen production in the system added by gold nanoparticles of 6 nm and 12 nm in diameter were obviously increased by about 17% and 9% in contrast to that in blank system. The experimental restdts indicate that gold nanoparticles could significantly enhance the bioactivity of hydrogen-producing microbe. |
