title: [Studies on reduction of Au3+ by bacteria for preparing gold catalyst].
abstract: The strain D01, screened from different source bacterial strains, has relatively strong ability of adsorbing Au3+. The strain D01 was identified as Bacillus megatherium D01 and still grew well in the medium containing 600 mg/L Au3+. The results of electrochemical reaction indicated that the strain D01 had a strong ability of reduction. It could reduce the Au3+/alpha-Fe2O3(precursor of the gold catalyst) to highly dispersive Au0/alpha-Fe2O3 catalyst which could catalyze the reaction of CO + O2-->CO2.
