| characterization and spatial distribution of methanogens and methanogenic biosignatures in hypersaline microbial mats of baja california. | well-developed hypersaline cyanobacterial mats from guerrero negro, baja california sur, sustain active methanogenesis in the presence of high rates of sulfate reduction. very little is known about the diversity and distribution of the microorganisms responsible for methane production in these unique ecosystems. applying a combination of 16s rrna and metabolic gene surveys, fluorescence in situ hybridization, and lipid biomarker analysis, we characterized the diversity and spatial relationships ... | 2008 | 18564187 |
