From IJSEM. Classification Higher order taxa Archaea, Euryarchaeota, Methanobacteria, Methanobacteriales, Methanobacteriaceae Species Genome: Methanobacterium aarhusense Description and Significance M. aarhusense is mesophilic, moderately halophilic, non-motile. Optimum growth temperature is 45°C. Grows well at pH of 7-5 and 8, however the optimum pH is unknown. Grows well in NaCl concentration range of 100 and 900mM. Genome Structure ! ! DNA G+C content is 34-39 mol %. The strain forms a distinct line of descent within this genus, with ! Methanobacterium oryzae (95·9 % sequence identity) and Methanobacterium bryantii (95.7% sequence ! identity). Cell and colony structure It is 5-18 μm long and 0-7 μm wide, filamentous. Metabolism M. aarhusense is a hydrogenotrophic methane, meaning that it converts hydrogen to energy as a way of metabolism. No growth or methane production was observed at 1 M NaCl. At 50 mM NaCl, growth and ! methane production were reduced. Ecology References: M. aarhusense is an autoroph. Optimal growth temperature is 45°C. Grows at pH 7-5 and 8. Can live in an CaCl concentration of 100 and 900 mM. Isolated from marine sediment in Aarhus Bay, Denmark. ! Shlimon, Adris Georgis, Michael W.
