氧化亚铁硫杆菌是一种重要的浸矿细菌,细胞固定化技术能将该菌限定在特定的区域内,增加细菌密度,有效提高其对Fe2+及低价态硫的氧化能力,且能提高细菌的稳定性和机械强度,并简化浸矿生产条件,最终提高工业生产的经济效益。该技术运用的材料包括有机材料、无机材料和人工合成材料;涉及到的固定化方法包括吸附法、包埋法、交联法、新固定化法等。固定化氧化亚铁硫杆菌技术在生物浸矿和生物脱硫领域具有良好的应用前景,该技术的发展为其实现产业化奠定了基础。

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 method...
