Molecular ecology of extremely halophilic Archaea and Bacteria.

摘要: Water bodies with NaCl concentrations approaching saturation are often populated by dense microbial communities. Red halophilic Archaea of the family Halobacteriaceae dominate in such environments. The application molecular biological techniques, particular use approaches based on characterization ribosomal RNA sequences, has greatly contributed to our understanding community structure hypersaline ecosystems. Analyses lipids extracted from environment have also provided useful information. This article reviews present saltern crystallizer ponds, Dead Sea, African soda lakes, and other water bodies. It was recently shown that red heterotrophic Bacteria genus Salinibacter, which no less salt-dependent salt-tolerant than most among Archaea, may coexist archaeal community. Our latest insights into their distribution ecosystems presented as well.
