Symbiosis of protozoa with hydrogen-utilizing methanogens.

摘要: The symbiotic interaction between bacteria and protozoa is a well-known phenomenon. Endosymbiosis of in the amoeba Pelomyxa was reported as early 1902 by Penard since then endosymbiosis has been described for variety many authors. Also episymbiosis observed frequently. However, surprisingly little known about physiological both partners such close association. This mostly because problems that arise characterizing bacteria, unknown nature excretion products one partner utilized other. discovery some unique fluorescent cofactors involved methane biochemistry which are specific methanogenic enabled recognition these microorganisms fluorescence microscopy. Using this technique, several associations anaerobic have found. aim paper to review field discuss possible functions symbiosis protozoa.
