Acidithiobacillus ferrooxidans is an important bacteria for ore-leaching. Cell immobi-lized technology can limit the bacteria within a particular region, increase the density of bacteria, effectively increase the oxidability on Fe2+ and low-valent sulfur,improve the stability and me-chanical intensity,simplify the conditions of production,and ultimately improve the economic benefits of industrial production. Materials used by this technique include the organic materials,inorganic materials and artificial synthetic materials. Immobilized methods involved include adsorption method, embedding cross methods, cross-linking methods,new immobilization methods,et al. The immobilized technology has a good application prospect in the field of bioleaching and bio-desulfurization,development of which establishes the foundation for realizing its industri-alization.
