以黄铁矿为能量来源对嗜酸氧化亚铁硫杆菌的高效培养进行了研究,并针对培养过程中黄铁矿的能量利用进行了分析.研究表明,在黄铁矿浓度10 g/L、接菌浓度15%和pH=2.0的条件下培养144 h后,嗜酸氧化亚铁硫杆菌细菌浓度达到6.4×108个/mL.在培养嗜酸氧化亚铁硫杆菌过程中单位质量黄铁矿提供的能量约为培养基中单位质量FeSO4·7H2O提供能量的34.7倍,通过黄铁矿可以实现对嗜酸氧化亚铁硫杆菌的高效培养.
Efficient Cultivation of Acidithiobacillus Ferrooxidans with Pyrite and Its Process Analysis
An efficient cultivation of acidithiobacillus ferrooxidans with pyrite as an energy source was studied and the utilization of pyrite energy during the cultivation was analyzed. It is found that acidithiobacillus ferrooxidans bacteria concentration was up to 6.4×108cell/mL after 144 h cultivation with pyrite concentration at 10 g/L, initial bacteria concentration at 15%and pH of 2.0.The energy provided by per unit mass pyrite during the cultivation of acidithiobacillus ferrooxidans was about 34.7 times that by per unit mass FeSO4·7H2O. It is concluded that acidithiobacillus ferrooxidans can be efficiently cultivated with pyrite.
