Biochemical activities of Thiobacillus ferrooxidans in the presence of activated carbon were studied under the shaking and stationary conditions using the 9K medium at pH 1.5. In the shaking condition, the biochemical activities of the bacterium were lower in the presence of activated carbon than in the absence. On the contrary, the activities were higher under the stationary condition. In the shaking condition, the bacteria were adsorbed onto the activated carbon according to the Langmuir isotherm. The adsorbed cells became inactive with regard to their ferrous ion-oxidizing and growth. Under the stationary condition, the oxidation rate of ferrous ion was higher in the presence of activated carbon than in the absence, because the cells gathered to the gas-liquid interface in the presence of activated carbon.
