Description and Significance
Describe the appearance, habitat, etc. of the organism, and why you think it is important.
Genome Structure
Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence?
Cell Structure and Metabolism
The cells of the regular cocci, Gram-positive Archaea are mostly associated in pairs, 0.5-0.8 mm in size. While multiple flagella are grown with 14 nm thick and 8–12 mm length, they are readily lost under stress conditions such as high-speed centrifugation and oxic environments. Cell wall of the cells about 30–70 nm thick can be observed in thin sections under electron microscopy. As is shown in study, cell wall can be resistant to SDS lysis, which indicates the cell wall is different from a single S-layer in spite of the fact that the S-layer is the only cell wall component in Archaea (Wikepedia http://en.wikipedia.org/wiki/S-layer). Methane is not produced from ethanol, methanol, 2-propanol, trimethylamine, 2-butanol, acetate, propionate or sodium butyrate, only using H2/CO2 or formate as substrates for methanogenesis in the strictly anaerobic condition. Na2S is used as a sulfur source. Growth will be inhibited with formate concentrations above 50 mM or Na2S concentrations above 0.1 mM.
Ecology and Pathogenesis
