Riffe aus Bakterien entdeckt

August 11, 2002 by admin 

Meereswissenschaftler finden riesige Riffe aus Methan-fressenden Mikroorganismen, die von großer Bedeutung für den globalen Kohlenstoffkreislauf sind.Riesige, bis zu vier Meter hohe Riffe aus Mikroorganismen, die sich von Methan ernähren, haben Wissenschaftler vom Bremer Max-Planck-Institut für marine Mikrobiologie sowie von der Universität Hamburg in Küstengewässern des Schwarzen Meers entdeckt (Science, 9. August 2002). Die Matten bestehen hauptsächlich aus extrem dichtgepackt lebenden Archaea und Sulfat-reduzierenden Bakterien, die in Symbiose poröse Stütz-Strukturen aus Kalziumkarbonat sowie beträchtliche Mengen an Biomasse produzieren. Diese Entdeckung ist von grundsätzlicher Bedeutung für unser Verständnis der frühen Perioden der Erdgeschichte und die Entstehung der Biosphäre.
