Meiothermus

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]

Characteristics

The Meiothermus genus was originally proposed to group together several moderately thermophilic organisms that were in the Thermus genus. Meiothermus are mostly distinguishable from Thermus by the lower bound of their optimum growth temperatures, 50-60 °C for Meiothermus and 70°C for Thermus. Also, in Meiothermus, the presence of two glycolipid bands is seen whereas Thermus species only contain one.[4]
