Query: NC_015680:663341 Pyrococcus yayanosii CH1 chromosome, complete genome
Lineage: Pyrococcus yayanosii; Pyrococcus; Thermococcaceae; Thermococcales; Euryarchaeota; Archaea
General Information: Pyrococcus yayanosii CH1 is the first obligate piezophilic hyperthermophilic archaeon isolated from the deep-sea hydrothermal site Ashadze on the mid-Atlantic ridge at a depth of 4,100 m. This organism grows within a temperature range of 80 to 108 degrees C and a hydrostatic pressure range of 20 to 120 MPa, with optima at 98 degrees C and 52 MPa, respectively.
Subject: NC_003552:4782635 Methanosarcina acetivorans C2A, complete genome
Lineage: Methanosarcina acetivorans; Methanosarcina; Methanosarcinaceae; Methanosarcinales; Euryarchaeota; Archaea
General Information: This wild-type strain (C2A; DSM2834) is the type strain of this species and was isolated from marine sediment. Anaerobic methane-producing archeon. This organism is a strictly anaerobic, nonmotile, methane-producing Archaea responsible for virtually all biogenic methane production, a process of critical importance as a key step in the global carbon cycle. This process results in the production of significant amounts of greenhouse gas. This organism is also important in production of alternative fuels and plays a role in both agricultural and waste treatment industry. Optimal growth occurs at pH 6.5-7.0.
