Species

Methanobacterium aarhusense

NCBI: Taxonomy

Description and significance

M. aarhusense is mesophilic, moderately halophilic, non-motile, meaning that it is a very picky microbe and prefers temperatures above 30℃. The optimum growth temperature is 45℃. It 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 structure and metabolism

It is 5-18 μm long and 0-7 μm wide, filamentous. It is a gram positive meaning that it has a thick peptidoglycan layer. M. aarhusense does not possess any pili or flagella, keep it non-motile. A large sample has been sequenced and contains 1333 base pairs.

M. aarhusense is a hydrogenotrophic methanogen, meaning that it converts hydrogen to energy as a way of metabolism and produces methane. No growth or methane production was observed at 1 M NaCl. At 50 mM NaCl, growth and methane production were reduced.

Ecology

M. aarhusense is a chemoautotroph, meaning that it produces complex organic compounds from simple substances. Optimal growth temperature is 45℃. Grows at pH 7-5 and 8. Can live in a CaCl concentration of 100 and 900 mM. Isolated from marine sediment in Aarhus Bay, Denmark. An artificial marine medium was created and it consists of three different solutions. Solution A consists of NaCl, 20; MgCl2.6H2O, 3; KCl, 0·7; NH4Cl, 0·2; KH2PO4, 0·2; CaCl2.2H2O, 0·2. Solution B consists of NaHCO3, 2·5 g in 30 ml demineralized water. Lastly, solution C consists of: 1·5 ml l−1 of 0·04 g Na2S.9H2O ml−1 demineralized water. On the agar, the colonies were circular and grayish, with white surrounding it.
