摘要:微生物驱动的碳循环是热泉生境各元素生物地球化学循环的核心部分.研究热泉生境驱动碳循环微生物及其代谢机制, 既有助于揭示地球早期生命起源与演化、探讨地外生命, 又具有重大的生物工程应用意义. 综合阐述了热泉生态系统驱动碳循环的功能微生物在系统发育学上的分布、功能基因的相对丰度和活性、功能群与环境因子(如温度、pH)的响应关系, 旨在了解热泉中驱动碳循环微生物的研究现状并为其后续研究提供理论基础

Abstract:Microbially mediated carbon cycles are the core component of biogeochemical element cyclingin hot spring ecosystem. Thus, the study of microbes and their metabolic mechamisms involved in carbon cycling in hot springs avails to reveal the origin and evolution of early life on Earth and to explore extraterrestrial life, and has great significance in bioengineering applications. Focus was given on the phylogenetic distribution of functional microorganisms involved in geothermal carbon cycling and their functional gene abundance, activity and composition in response to environmental factors (e.g., temperature, pH).This review aimsto understand the current situation of microbes driving carbon cycles in hot springs and provide theoretical basis for~futureresearch
