Adsorption of a mixture of Thiobacillus thiooxidans and Thiobacillus ferrooxidans onto copper-containing furnace dust

The Langmuir adsorption parameter X(Am) of a mixture of culture of Thiobacillus ferrooxidans and Thiobacillus thiooxidans indicates that these bacteria have preferential and competitive adsorption sites on furnace dust. The constant K(A) of the mixture significantly larger than that of each component, suggesting that a synergistic effect may occur in the binding of these bacteria to the dust.
