摘要
为了减少氧化亚铁硫杆菌培养过程中黄钾铁矾沉淀的生成,通过改变培养基的pH值、菌种的培养温度、不同的菌种接种量及优化培养基组分等方法,确定出黄钾铁矾沉淀生成量最少的培养条件,即培养基pH值为2.0,培养温度为30℃,菌种接种量为10%,最佳培养基组分K2HPO4为0.25 g/L,KH2PO4为0.195 g/L。此条件下即能保持菌种的良好活性,又能使产生沉淀量降至2.27 g/L。
In order to reduce jarosite precipitate generated in the growth process of acidithiobacillus ferrooxidans, b changing Y the pH value of the culture, the cuhivation temperature, different inoculation quantity and optimization culture, composition method, the conditions with the least amount of jarosite precipitation production were determined that the medium pH value was 2.0, temperature was 30℃, inoculation quantity was 10%, the best component medium was K2HPO4 0.25 g/L, and KH2PO4 0. 195 g/L. The conditions can maintain activity of the bacteria, and can make the precipitation amount down to 2.27 g/L.
