Abstract: The growth behavior of Thiobacillus ferrooxidan (T.f.) in high concentration ferrous ion solution was studied and the change of pH, potential and oxidation of ferrous ions in the solution were also investigated. It is found that T.f. can grow normally under the conditions of [Fe2+]<70 g/L, pH=1.6~2.0 and suitable inoculum of 10%. The final bacteria density after 10 d culture may be up to (0.8~31.6)′107 cell/ml.
Key words: Thiobacillus ferrooxidan, growth behavior, ferrous ion
摘要: 测定了氧化亚铁硫杆菌在高铁离子浓度下的生长曲线、溶液pH的变化、T.f.菌对亚铁氧化情况及溶液氧化还原电位(Eh)的变化规律. 实验发现T.f.菌在[Fe2+]<70 g/L及pH=1.6~2.0、接种量10%的条件下生长良好,培养时间为10 d后细菌浓度可以达到(0.8~31.6)′107个/ml.
