自然环境中细菌的生存方式及其群落特征

Abstract

细菌在环境中是以群落的形式存在的,群落中的细菌有多种生存方式.当处于适宜的环境中,细菌通过互作而快速生长,而营养物质的消耗又造成细菌之间的竞争.不同细菌通过复杂的作用形成的群落容易受到外界环境的影响,并且特殊的功能基因也改变了原有的群落结构.细菌群落在环境中有着重要的生态功能及理论与应用价值.本文介绍了细菌的生存方式,结合作者相关研究阐述了细菌群落结构及其生态功能,并予以展望,旨在为细菌群落的深入研究、开发和应用提供参考.

Bacteria in the environment live in communities with multiple survival modes.Bacteria in a suitable environment grow rapidly through cooperation,whereas nutrient consumption cause competition.Bacterial communities are vulnerable to the impact of the external environment,and the special functional gene can also change the community structure.Bacterial communities have important ecological functions in the environment and they are both complex and valuable.This paper,by combining the work of our group with literature,tried to elaborate on bacterial survival modes as well as the formation and ecological function of bacterial communities,to provide a reference for the study of bacterial community and to look into the future direction of this field of research.
