中文摘要：
二典型表面活化剂， Tween-80 和钠异丁基黄原酸盐(NaIBX ) 完成，与生长和新种类 Acidithiobacillus albertensis BY-05 的氧化硫的活动上的不同集中，一个嗜酸的氧化硫的细菌，被调查。结果显示两表面活化剂能提高生长和 A 的氧化硫的活动。仅仅在一些特殊集中的 albertensis BY-05，例如， 10 ? 410 ? 为 NaIBX 的 8 g/L 并且比 10 低 ? 为 Tween-80 的 8 g/L，但是被禁止并且在更高的集中甚至有害。两表面活化剂不能被 A 使产生代射变化。albertensis BY-05。在细菌和硫粒子之间的接触可能依赖于细胞外的物质和表面活化剂，哪个提供为细菌改进附件到硫粒子表面的 amphiphilic 环境。这些数据能为扩大两 A 的应用是重要的。为硫化物矿物质的工业 bioleaching 的 albertensis BY-05 和一些典型表面活化剂。
英文摘要：
Effects of two typical surfactants, Tween-80 and sodium isobutyl-xanthate （NaIBX）, with different concentrations on the growth and sulfur-oxidizing activities of a new strain Acidithiobacillus albertensis BY-05, an acidophilic sulfur-oxidizing bacterium, were investigated. The results indicate that both surfactants can enhance the growth and sulfur-oxidizing activities of A. albertensis BY-05 only at some special concentrations, e.g., 10^-4-10^-8 g/L for NaIBX and lower than 10^-8 g/L for Tween-80, but were inhibited and even harmful at higher concentrations. Both surfactants can not be metabolized by A. albertensis BY-05. The contact between the bacteria and the sulfur particles may be dependent upon both the extracellular substance and the surfactants, both of which provide the amphiphilic environment improving the attachment for bacteria to the sulfur particles surface. These data could be significant for enlarging the applications of both A. albertensis BY-05 and some typical surfactants for industrial bioleaching of sulfides minerals.
