2 English reference sulfur bacteria
Note that sulfur bacteria are microorganisms that can oxidize hydrogen sulfide, elemental sulfur, ferrous sulfide or inorganic sulfide to produce sulfate, which can be divided into sulfur bacteria and sulfide bacteria.
Sulfur bacteria can oxidize sulfides such as hydrogen sulfide and sulfur into sulfuric acid, and can use the energy released during sulfur oxidation or vulcanization to assimilate carbon dioxide for growth. Distributed in soil, fresh water, salt water, hot springs and sulfur mines. There are various types of bacteria, some are filamentous, such as Beggiatoa and Thiothrix, and some are unicellular, such as achromatous bacteria. Some rely on flagella to move, such as Thiobacillus and Thiobacillus, and some rely on flagella-free sliding movement, such as some Thiobacillus; Some are strictly autotrophic, and some are facultative autotrophic; Although some bacteria can oxidize sulfide into sulfuric acid, they will not accumulate sulfur particles in the body, such as many kinds of thiobacillus, which are customarily called sulfide bacteria. However, some bacteria can accumulate sulfur particles in the body. When the environment lacks hydrogen sulfide and other things, the sulfur in the body is further oxidized into sulfuric acid, which is customarily called sulfur bacteria. All of the above are self-supporting. In addition, there are autotrophs that use light energy. Bacteria contain photosynthetic pigments, such as chromobacteria and green bacteria. They are also called sulfur bacteria under anaerobic conditions. In the process of anaerobic photosynthesis with photosynthetic pigments, they oxidize hydrogen sulfide into sulfuric acid and form sulfur particles inside or outside cells. It usually grows well in an anaerobic environment with sufficient light and hydrogen sulfide. The activity of sulfur bacteria in soil can improve the solubility of various minerals in soil and inhibit the growth of some acid-sensitive pathogens. Applying sulfur in some soils can improve soil acidity by promoting the activity of sulfur bacteria, thus improving alkaline soil. Sulfur bacteria can also be used for bacterial leaching.
