Acetate is an important substrate for methanogenesis in anaerobic bioreactors and two-thirds or more of the methane produced in anaerobic bioreactors is derived from acetate. All described acetate-using methanogens belong to the order Methanosarcinales. Among these, Methanosaeta species can be distinguished from members of the other genera by their exclusive use of acetate as a substrate for producing methane and by their rod-shaped cells, instead of coccoid or pseudosarcinal cells such as those of Methanosarcina species. In addition, in contrast to Methanosarcina species, Methanosaeta strains are favoured in environments with low concentrations of acetate. Methanosaeta harundinacea (strain 6Ac) is an extremely halophilic archaeon isolated from an upflow anaerobic sludge blanket reactor treating beer-manufacture wastewater in Beijing, China. Cells are rod-shaped and non-motile, occurring singly or in pairs; however, at high cell density the cells are arranged in long chains within a common sheath. M.harundinacea uses acetate exclusively for growth and methane production. The specific growth rate is 0.030/h when growing in acetate (20 mM) at 37 degrees Celsius. The temperature range for growth is between 25-45 degrees Celsius, with the fastest growth at 34-37 degrees Celsius. The pH range for growth and methane production is 6.5-9.0, with the fastest growth at pH 7.2-7.6. (Adapted from PMID: 16403877).
