摘　　要：极地由于其独有的地理及气候特征 ,生存于其中的微生物具有独特的分子生物学机制和生理生化特性。极地的低温对生存于其中的微生物产生广泛而深刻的影响 ,人们对于极地微生物对这一环境因子的适应机制研究得也最为详尽。本文从酶分子水平、细胞膜、细胞质等各个角度简述了近年来国内外有关极地微生物低温适应性的分子机制 。Polar microorganisms possess specially genetic, physiological and biochemical properties for the uniquely geographic and climatic features in Antarctic and Arctic. The cold temperature of polar environment has a wide ranging influence on all of the microbial ecosystems of this region. Adaptation mechanisms of polar microorganisms for this environmental factor are studied in detail in recent years. This paper briefly describes the advances in molecular mechanism of cold adaptation of polar microorganism in aspects including low temparature enzymes, cell membrane, cytoplast and so on.
