What are chemoautotrophic microorganisms? How do they synthesize cellular matter?

This microorganism can synthesize inorganic matter from the environment into organic matter that it needs, and this process requires specific enzymes that are involved in chemical reactions in the microorganism! For example, nitrifying bacteria can convert NO2 in the atmosphere into substances they need, and produce microorganisms that can use carbon dioxide as a carbon source to grow using the energy released during the oxidation process of inorganic compounds such as ammonium, nitrite, hydrogen sulfide, and iron ions. The main taxa are:

Sulfur bacteria, nitrifying bacteria, iron bacteria, etc. Their growth needs to take place under aerobic conditions. Most methanogens can live autotrophically, they use hydrogen as an energy source, carbon dioxide as a carbon source to grow, the product is methane, we call anaerobic autotrophic fine nitrite bacteria (also known as ammonia-oxidizing bacteria), ammonia oxidized into nitrous acid.

Nitric acid bacteria (also known as nitrifying bacteria) oxidize nitrite to nitric acid, and use the energy released by oxidation to synthesize inorganic matter into organic matter for their own use, that is, chemoautotrophic microorganisms.

The amount of bacteria is needed for one's own life activities....

Microorganisms that use carbon dioxide as a carbon source and use the energy released during the oxidation process of inorganic compounds such as ammonium, nitrite, hydrogen sulfide, iron ions, etc. The main groups are: sulfur bacteria, nitrifying bacteria, iron bacteria, etc.

1 Photo-inorganic autotrophic type (photoautotrophic type).

CO2 can be used as the sole or main carbon source; photosynthesis to obtain the energy needed for growth; Inorganic substances such as H2, H2S, S, H2O, etc. are used as hydrogen donors or electron donors to reduce CO2 to cellular matter;

For example, algae and cyanobacteria, like plants, use water as an electron donor (hydrogen donor) to carry out oxygen-producing photosynthesis and synthesize cellular matter. Red sulfur bacteria, which use H2S as an electron donor, produce cellular material with the production of sulfur.

2 Photo-organic heterotrophic type (photo-heterotrophic type).

CO2 cannot be used as the primary or sole source of carbon; Organic matter is used as a hydrogen donor, and light energy is used to reduce CO2 to cellular matter. Most of them require exogenous growth factors for growth;

For example, some bacteria in the genus Rhodospira can use isopropanol as a hydrogen donor to reduce CO2 to cellular material while accumulating acetone.

3 Chemoinorganic autotrophic type (chemoautotrophic type).

The energy required for growth comes from the chemical energy released during the oxidation of inorganic substances; When CO2 or carbonate is used as the sole or main carbon source for growth, inorganic substances such as H2, H2S, Fe2+, NH3 or NO2- are used as electron donors to reduce CO2 into cellular matter.

4 Chemoheterotrophic (Chemoheterotrophic).

The energy required for growth comes from the chemical energy released during the oxidation of organic matter; The carbon sources required for growth are mainly some organic compounds, such as starch, sugar, cellulose, organic acids, etc.

5 Auxotrophic type.

After some strains have mutations (natural mutations or artificial mutagenesis), they lose the ability to synthesize a certain (or some) substances (usually growth factors such as amino acids and vitamins) that are essential for the growth of the strain, and the substances must be obtained from the external environment in order to grow and reproduce.

Sergei Winogradsky (1856-1953) studied the bacterium Beggiatoa and determined that it uses the inorganic H2 S as an energy source and CO2 as a carbon source. He was the first to propose the concept of autotrophs and their relationship to the natural cycle of the band.

Winograski found that there were filamentous substances growing at the mouth of the channel where the sulphur springs (rich in H2S) flowed out, and they consisted of a large number of Bézhattosia. He also found that the sulfur particles in the body disappeared after starvation for a period of time with the bacterium Bergean, but reappeared after giving H2 s. After a few small tests, he speculated that sulfur oxidized in the bacterium Bergeatola, and that these oxidation processes were the main energy of the bacterium**.

Later, because the study of sulfur bacteria interfered with the process, Sergei turned to the study of nitrifying bacteria.

It's up to someone else to see if it's useful. That's all I know.

Correct answer: ABCD

Answer] :d sulfur bacteria obtain energy through inorganic sulfides such as sulfur oxide and hydrogen sulfide, and the carbon source is inorganic carbon destroys the virtual source of land sedans such as carbon dioxide, so it is chemoautotrophic type. Viruses, on the other hand, live parasitic lives and cannot produce nutrients on their own.

Molds are chemoheterotrophic microorganisms. Cyanobacteria are photoautotrophic microorganisms.

) is a bifunctional biotrophic nutrient of some chemoautotrophic microculture rolling cavity organisms.
