Electini

The the genus group electini split from its ancestor genus group octhermas. While it still lives in the same habitats as its ancestor such as deep sea vents and hot springs it has developed to consume a different food source. Like Earth's Shewanella oneidensis, it consumes Manganese. Specifically it reduces metal ions in the manganese. It is capable of surviving and proliferating in both aerobic and anaerobic conditions. Unlike its ancestor they are more diamond in shape. Their thick cell walls protect them from the heat. When growing they make a biofilm around anything they grow on. Some species even creating grid-like mats. They reproduce through binary fission. Electini are considered a DMRM (Dissimilatory Metal-Reducing Microorganisms). DMRMs are microorganisms that can perform anaerobic respiration utilizing a metal as terminal electron acceptor rather than molecular oxygen (O2), which is the terminal electron acceptor reduced to water (H2O) in aerobic respiration. The most common metals used for this end are iron [Fe(III)] and manganese [Mn(IV)], which are reduced to Fe(II) and Mn(II) respectively, and most microorganisms that reduce Fe(III) can reduce Mn(IV) as well. But in electini they specialize in Manganese. In simple term they "eat and breathe" electricity from heavy metals.
