Query: NC_015730:3853065 Roseobacter litoralis Och 149 chromosome, complete genome
Lineage: Roseobacter litoralis; Roseobacter; Rhodobacteraceae; Rhodobacterales; Proteobacteria; Bacteria
General Information: This type strain for the species was collected from seaweed and isolated by direct plating. Capable of performing aerobic anoxygenic photosynthesis. Photosynthesis genes are located on a plasmid, which is unusual for aerobic anoxygenic phototrophs.
Subject: NC_015474:644552 Pyrococcus sp. NA2 chromosome, complete genome
Lineage: Pyrococcus; Pyrococcus; Thermococcaceae; Thermococcales; Euryarchaeota; Archaea
General Information: Pyrococcus has similar characteristics of other thermoautotrophican archaea such as Archaeoglobus, and Methanococcus in the respect that they are all thermophilic and anaerobic. Pyrococcus differs, however, because its optimal growth temperature is nearly 100 °C and dwells at a greater sea depth than the other archaea. Studying Pyrococcus helps give insight to possible mechanisms used to endure extreme environmental conditions like high temperatures and high pressure.
