摘要
随着全球人口、资源与环境问题的加剧,人类把目光投向海洋。深海包含在极酸、极碱、极热、极冷、高盐、高压等极端环境下能够生存繁衍的微生物。与陆地微生物比较,它们可能具备某些不同的代谢途径和遗传背景。对极端环境微生物生存与适应机制的研究将加深我们对深海微生物乃至深海生物圈对全球气候影响的理解,也将促进我们对深海微生物资源和深海矿产资源的开发。在综合以往对各种极端环境下微生物研究的基础上对深海微生物的生存及适应机制进行了分析与阐释,为深海微生物的研究提供参考。
With the developing of the paradox of population, resources and environment, the marine is coming into the research focus of the world. Deep sea is an special dark world containing the extremophiles which can endure extreme environment, such as extreme acid, extreme alkaline, extreme hot, extreme cold, extreme high salinity and extreme pressure, etc. In contrast to the terrestrial microorganisms, these microbes possess some different mechanism properties or genetic properties. The research about the adaptation mechanism of extremophiles will promote the understanding of deep sea biosphere and the global climate as well as the exploitation of the deep sea microbes and minerals resources. The review analyzed and elucidated the survival and adaptation mechanisms on the base of the former extremophiles research, which will offer some references for the study of deep sea microbes in the future.
