title: [Study on the rejuvenating by isolation and the immobilization of Thiobacillus ferrooxidans].
abstract: A strain of Thiobacillus ferrooxidation T1 with stronger oxidation ability and more exuberant vitality was isolated from the liquid with regressive Thiobacillus ferrooxidans by method of dilution butteron on plate. A fixed-bed bioreactor was constructed by immobilized cells of Thiobacillus ferrooxidans with H-2 carriers. In the state of bioreactor operation, a maximum Fe2+ oxidation rate of 7.67g[Fe2+] x h(-1) x L(-1) was attained. We studied the precipitates formed on the surface of the carriers during the operation of the bioreactor. By X-ray diffraction analyses we proved the precipitates were jarosite.
