The Thermodesulfobacteriota, or Desulfobacterota,[3] are a phylum of Gram-negative bacteria. Many representatives are sulfate-reducing bacteria, others can can grow by oxidation or disproportionation of various sulphur species. They have highly variable morphology: vibrio, rods, cocci, and filaments.[3]

Ecology and metabolism

[edit]

Sulfate reducers utilize sulfate as a terminal electron acceptor, deriving energy from the oxidation of organic compounds or hydrogen gas. By reducing sulfate, many Thermodesulfobacteriota contribute to the sulfur cycle.[3]

Dissulfuribacter thermophilus (Dissulfuribacteria) does not reduce sulfate and instead disproportionates elemental sulfur and other intermediate sulfur species.[4]

A pathogenic intracellular thermodesulfobacteriote has been identified in 2008.[5]
