Ecology and Physiology of Some Anaerobic Bacteria from the Microbial Sulfur Cycle

摘要: Considering the conditions under which different groups of microorganisms involved in sulfur cycle are active, it is advisable to differentiate an aerobic and anaerobic part. Under conditions, reductive part assimilatory sulfate reduction green plants. The reduced organic Compounds ultimately liberated during decomposition substances from plants animals become reoxidized by chemoautotrophic mixotrophic colorless bacteria (e. g., Thiobacilli, Beggiatoa). entirely mierobial. Sulfate used as electron acceptor energy-conserving, dissimilatory various sulfate-reducing bacteria. sulfide arising this process either light phototrophic or purple bacteria, hydrogen reaches regions then chemically biologically oxidized via thiosulfate (Fig. 1).
