Sulfur-reducing bacteria are microorganisms able to reduce elemental sulfur (S ) to hydrogen sulfide (H2S). These microbes use inorganic sulfur compounds as electron acceptors to sustain several activities such as respiration, conserving energy and growth, in absence of oxygen. The final product or these processes, sulfide, has a considerable influence on the chemistry of the environment and, in addition, is used as electron donor for a large variety of microbial metabolis… WebNov 3, 2016 · The green sulfur bacteria, or Chlorobiaceae, comprise one of the most unique families of photosynthetic organisms.
