硒是人和动物必需的一种微量元素，但是高浓度硒盐会对有机体产生毒害作用，同时会污染环境。而细菌合成的纳米硒无毒、稳定，具有较高的生物活性，在纳米硒生产和硒污染治理等方面应用潜力巨大。本文主要综述了纳米硒的特征及应用，分析了碳氮源、氧气、温度、pH等一系列因素对细菌产生纳米硒过程的影响，阐述了细菌还原合成纳米硒的初步研究机理，并探讨了该研究未来的关注点，为生物纳米硒的广泛应用提供参考。

Selenium (Se)is a kind of essential trace element for people and animal, while ionic state of selenium is toxic with high concen-trations and will cause the selenium pollution. Nano-selenium is stable, nontoxic with higher biological activity. Application of bacteria re-ducing selenite or selenate to biological nano-selenium has great potential in selenium pollution control and nano-selenium production. This review summarizes the research progress of the red elemental nano-selenium reduced by bacteria including characteristics and appli-cation of nano-selenium, effects of carbon and nitrogen source, oxygen, temperature and pH in bacteria nano-selenium production, and molecular mechanisms of nano-selenium reduced by bacteria.
