摘要:
好氧不产氧光合细菌(aerobic anoxygenic photosynthesis bacteria,AAPB)是广泛分布于海洋、湖泊及河流等典型水域生境中的异养原核生物,能够以环境中有机物为营养物质来获取细胞生长及代谢所需的能量,同时借助自身独特的菌绿素完成光合作用产能但不合成氧气,在物质循环与能量流动中扮演着重要角色.近年,越来越多的AAPB种属被陆续报道,基于光合基因,例如光合反应中心M亚基(pufM)的分子系统发育分析显示,大部分AAPB属于α-、β-及γ-变形菌,且丰度及多样性随生境的不同而呈现时空地理格局异质性.本文对AAPB的栖息环境与生长特性、丰度与分布、生态功能以及环境驱动因子等方面的研究进展进行了回顾和综述.目前,针对水库生态系统AAPB的研究鲜见报道,作者建议开展水库生境中AAPB多样性分布、环境驱动因素及生态功能研究,丰富对于水生生态系统中功能微生物种群生态结构与代谢功能的认识.

Abstract:
Aerobic anoxygenic photosynthesis bacteria (AAPB) are heterotrophic prokaryotes widely distributed in typical water habitats such as oceans, lakes, and rivers. They can use organic matter in the environment as nutrients to obtain energy for cell growth and metabolism absorb organic matter from environment to maintain cell growth and metabolism but also rely on its own unique chlorophyll to complete the photosynthesis without oxygen production, playing an important role in water material circulation and energy flow. In recent years, more and more AAPB species have been reported one after another. Based on molecular phylogenetic analysis of photosynthetic genes such as the M subgene (pufM) of the photosynthetic reaction center, most AAPB belong to Alpha-, Beta-, and Gamma-proteobacteria. Moreover, the abundance and diversity of AAPB show heterogeneity in spatial and temporal geographic pattern varying with habitats. This article reviews and summarizes the research progress on AAPB's habitats and growth characteristics, abundance and distribution, ecological functions, and environmental drivers. At present, there are few reports on AAPB in reservoir ecosystems. The author proposes to conduct research on AAPB diversity distribution, environmental driving factors and ecological functions in reservoir habitats to enrich the understanding of the ecological structure and metabolic functions of functional microbial populations in aquatic ecosystems.
Key words:  Aerobic anoxygenic photosynthesis bacteria (AAPB)  aquatic ecosystems  abundance and distribution  pufM gene  driving factors
