Fluorescence in situ hybridization (FISH) analysis of bacteria and archaea in chemostat.

Authors established a chemostat cultivation method for a mesophilic methanogenic consortium degrading long-chain fatty acids. Left panel shows a phase-contrast image of microorganisms in chemostat. Right panel shows bacteria (red) and archaea (green) visualized by FISH using archaeal- and bacterial-domain-specific probes. Authors detected the following major groups of methanogen within the archaeal community: the aceticlastic genera Methanosaeta and Methanosarcina and the hydrogenotrophic genus Methanospirillum.
