摘要/Abstract

摘要： 嗜酸氧化硫硫杆菌常被应用于生物湿法冶金，金属污泥的处理等领域，但其天然菌株的产酸能力有限。本试验对从某矿酸性水中分离出的天然嗜酸氧化硫硫杆菌进行了提高产酸能力的研究，对不同初始pH值和能源物质对其产酸能力的影响进行了试验，同时采用微波和紫外线诱导育种的方法使嗜酸氧化硫硫杆菌的产酸能力得到进一步提高。

Abstract: Acidithiobacillus thiooxidans are often used in the biological hydrometallurgy and metal-containing sludge treatment fields, but their natural bacterial strains have a limited acid-producing capacity. In this experiment, the improvement of the acid-producing capacity of the natural Acidithiobacillus thiooxidans separated from the acid drainage of a mine was studied, including the effect of different initial pH values and energy source of substrate on the acid-producing capacity. Meanwhile, microwave and ultraviolet induction breeding were adopted to further improve the acid-producing capacity of Acidithiobacillus thiooxidans.

Key words: Acidithiobacillus thiooxidans, Inducement, Acid-producing capacity
