铁矿物形成过程中的细菌作用研究

研究表明，细菌作用下形成针铁矿、水针铁矿和赤铁矿的过程中，细菌对矿物的作用贯穿于溶解吸附、络合、转换、结晶成核的全过程。细菌对矿物的作用具专属性。细菌作用不仅使原来矿物产生溶解、形成新矿物，生物化学显微环境的差异也可导致生成矿物的不同。同时细菌作用对矿物晶体结构、表面性质也产生影响。

A Study on the Role of Bacterial Action in the Formation of Iron Minerals

A study of the formation of goethite, hyrogoethite and hematite under the bacterial action indicates that the bacterial action includes the whole process of solution and adsorption, complexation, transformation and crystallization-nucleation. The action of bacteria on minerals is characterized by specialization. Bacterial action not only dissolves the original minerals and form new minerals but also produces the differences in microenvironments of organic chemistry, which can help to form new different minerals. This is called organic crystallization action. At the same time, bacterial action affects the crystalline structures and the surface properties of the minerals.
