石生微生物研究进展

摘要

Lithophilous microorganisms ( LM) are a sort of microbial communities living in , or on, the rocks with the support of autotrophic microbes .The capability to better adapt to extreme environments helps them distributed all over the globe.The study of lithophilous organisms significantly improved the understanding in ecological adaptive mecha -nisms of lives in extreme environments , extraterrestrial life detection , and protection of stone relics .Yet, the study of LM is rarely reported in China .Classification of LM , distribution , research methods and ecological adaptation and other aspects were reviewed in this paper , to discuss the existing problems of LM study and promote the researches in the related fields .%石生微生物是一类自养微生物支持下的在全球广泛分布、能较好适应极端自然条件的岩石生境微生物及微生物群落.石生生物的研究对极端环境生态适应机制、探索地外生命以及保护石质文物等方面都有重要指导作用,然而我国对石生微生物的研究罕有报道.本文从石生微生物的分类、分布、研究方法、生态适应等方面的研究进展进行综述,对石生微生物研究存在的问题进行探讨,为我国相关领域的研究提供参考.
