Quorum Sensing in Marine Microbial Environments
Annual Review of Marine Science ( IF 17.3 ) Pub Date : 2017-01-03 00:00:00 , DOI: 10.1146/annurev-marine-010816-060656

Quorum sensing (QS) is a form of chemical communication used by certain bacteria that regulates a wide range of biogeochemically important bacterial behaviors. Although QS was first observed in a marine bacterium nearly four decades ago, only in the past decade has there been a rise in interest in the role that QS plays in the ocean. It has become clear that QS, regulated by signals such as acylated homoserine lactones (AHLs) or furanosyl-borate diesters [autoinducer-2 (AI-2) molecules], is involved in important processes within the marine carbon cycle, in the health of coral reef ecosystems, and in trophic interactions between a range of eukaryotes and their bacterial associates. The most well-studied QS systems in the ocean occur in surface-attached (biofilm) communities and rely on AHL signaling. AHL-QS is highly sensitive to the chemical and biological makeup of the environment and may respond to anthropogenic change, including ocean acidification and rising sea surface temperatures.

海洋微生物环境中的群体感应

群体感应(QS)是某些细菌所使用的一种化学通讯形式,它调节着广泛的生物地球化学上重要的细菌行为。尽管近40年前在海洋细菌中首次发现QS,但直到最近十年才对QS在海洋中的作用感兴趣。显然,QS受信号如酰化高丝氨酸内酯(AHL)或呋喃糖基硼酸酯二酯[autoinducer-2(AI-2)分子]的调节,参与了海洋碳循环中的重要过程,对健康有影响。珊瑚礁生态系统,以及一系列真核生物与其细菌同伴之间的营养相互作用。海洋中研究最深入的QS系统出现在表面附着的(生物膜)群落中,并且依赖于AHL信号传导。
