Antimony (Sb) is a highly toxic heavy metal which widespreadly exists in nature.With the increasing development of industry,the soil,water and agricultural products are severely polluted by antimony in some regions of our country.As an environmental pollutant,antimony poisoning can lead to heart failure,human diseases such as liver necrosis.Some organisms in nature,especially the microorganisms can grow in the high concentration of antimony,and can even use the element as an energy material,so the microorganisms play an important role in the cycle of earth’s materials.Study on metabolic mechanism of antimony has important practical significance to protect environment and human health.This study reviewed the researches of Sb distribution in the environment,the pollution status,microbial metabolism of antimony and bioremediation.At the same time it suggests that future researches should strengthen the following three aspects:(1) isolating more antimony resistance or antimony oxidizing microorganisms; (2) identifying more antimony resistant or oxidizing genes; (3) exploring microbial techniques to remediate Sb contaminated soil and water.
