Thermophiles at Grand Prismatic Spring

Meiothermus is a genus of Deinococcota bacteria.[1] [2] Members of Meiothermus can be reliably distinguished from other genera in the family Thermaceae as well as all other bacteria by the presence of three conserved signature indels (CSIs) found in the proteins: 5-methyltetrahydrofolate–homocysteine methyltransferase, cadmium transporter and polynucleotide phosphorylase and are exclusively shared by species of this genus.[3] Meiothermus is also different than the Thermus genus, which it was originally a member of, in their optimum growth temperatures, with Meiothermus being able to grow in colder environments. Meiothermus was first isolated with Thermus in alkaline and neutral hot springs in Kamchatka, Russia and Yellowstone National Park, USA.
