Thiobacillus 박테리아의 흡착에 대한 온도 및 혼합배양의 영향 = An Effect of Temperature and Mixed Culture on the Adsorption of Thiobacillus Bacteria

다국어 초록 (Multilingual Abstract)

The adsorptions of Thiobacillus ferrooxidans, Thiobacillus thiooxidans and their mixed cultures onto the copper-containing furnace dust were examined in an acidic medium solution. Adsorption of T. ferrooxidans and T. thiooxidans fits well to Langmuir isotherm. The maximum adsorption amount, XAm and adsorption equilibrium constant, KA gradually increase as the temperature increases from 5 ℃ to 35 ℃. The X_(Am) value of the mixed culture is larger than that of any single culture but slightly smaller than the sum of each bacterial component value, which indicates that these two bacteria have both of some preferential and competitive adsorption sites on furnace dust. The adsorption affinity, K_A of mixed culture is about 4.5 or 3.4 times larger than that of T. thiooxidans or T. ferrooxidans, respectively, which suggests that the synergistic effect exists in their bindings.
