Nickel is one of the necessary nutrition elements for some microorganism and higher plants and plays an important role in their life. However, nickel in high dose is also a extreme toxic element to biology. A great deal of research results show that nickel pollution in soil can lead to serious impacts on microorganisms. The growth, metabolism, soil enzyme activity, communities diversity of microorganism can be affected in the soil polluted by nickel. However, using microbial resistances and endurances of some bacterial species to develop the bioremediation measures treating polluted soil will be possible. Some suggestions including the polluted soil microbiological assessment, the soil environment capacity, the microbial technology and the integrated treatment technology were proposed for the future works.
