| 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.
