Abstract:
:A new ciliate species (Cyclidium porcatum) is the first freshwater anaerobic scuticociliate to be cultured and described. It contains a unique tripartite structure consisting of hydrogenosomes (confirmed by cytochemical staining for hydrogenase), interspersed with methanogens (confirmed by auto fluorescence and in situ hybridisation with an archaeobacterial 16S rRNA-specific probe) and unidentified eubacteria (confirmed with a eubacterial 16S rRNA-specific probe). This complex structure is stable and persistent, indicating that it is an anaerobic symbiotic consortium incorporating three functional partners.
