古菌细胞膜脂在古菌群落组成及其对环境响应研究中的应用
Applications of archaeal membrane lipids in investigating archaeal community composition and its responses to environmental factors
摘要
Abstract
Archaea, as the third life form distinct from bacteria and eukaryota, widely distribute in various kinds of habitats, and play important roles in the biogeochemical cycles of carbon and nitrogen and in ecosystem functioning. As the biomarker of archaea, archaeal membrane lipids can be used to investigate the archaeal community composition and its responses to the environment. This paper introduced the structural characteristics of archaeal membrane lipids and the differences in the membrane lipids composition among different archaeal communities, and discussed the feasibility of using archeal membrane lipids in depicting archaeal community composition. The abundance of archaeal membrane lipids in the environment could be used to characterize the biomass of archaea, and the related results could complement and ascertain each other with the DNA-based bio-molecular approaches on the accuracy, analysis efficiency, and cost. Based on the description of the difficulties and importance of using archaeal membrane lipids to analyze the composition and abundance of archaeal communities, and by linking to the environmental factors such as temperature and pH that affected the archaeal community composition, the relationships between archaea and their habitats were further expatiated, and the evolution process of archaeal communities and its application prospects in the studies of geochemistry and geological events were analyzed.关键词
