Query: NC_017954:471000 Thermogladius cellulolyticus 1633 chromosome, complete genome
Lineage: Thermogladius cellulolyticus; Thermogladius; Desulfurococcaceae; Desulfurococcales; Crenarchaeota; Archaea
General Information: Obligate anaerobe. Grows optimally at a temperature of 84 deg C and pH 7.1, isolated from the hot spring in the Uzon Caldera in Kamchatka (Russia). Capable of growing by fermentation not only on proteinaceous substrates but also on cellulose. Elemental sulfur is not obligately required but stimulates growth and is reduced to H2S.
Subject: NC_009975:1203372 Methanococcus maripaludis C6, complete genome
Lineage: Methanococcus maripaludis; Methanococcus; Methanococcaceae; Methanococcales; Euryarchaeota; Archaea
General Information: This strain was isolated from intertidal sediments. Methanococcus maripaludis is a rapid growing hydrogenotrophic methanoarchaeon common in salt marshes, marine and estuarine environments in the Southeastern U.S.A. Methanococcus maripaludis is an obligately anaerobic, mesophilic, methane-producing archaeon. Growth on hydrogen and carbon dioxide results in the production of methane as a waste product. M. maripaludis stands out among methanogenic archaea as an ideal model species because of fast reproducible growth and effective genetic tools.
