In nature, chemically synthesized bacteria are everywhere. For example, nitrifying bacteria are a kind of bacteria that can oxidize inorganic nitrogen compounds and obtain energy from them, thus synthesizing CO2 into organic matter. The process of synthesizing organic matter by nitrifying bacteria is as follows:

2nh33o2-2hno2 2h2o energy

2 HNO2O2-2 HNO3 energy

6 CO2·6H2O-c6h 12o 6·6o 2

The first two equations explain the oxidation and energy release process of ammonia and nitrous acid, and the last equation shows that nitrifying bacteria use the energy released by the first two equations. The process of synthesizing CO2 and H2O absorbed from the outside into glucose.

Nitrifying bacteria actually include nitrifying bacteria and nitrifying bacteria, and no nitrifying bacteria can directly convert ammonia into nitric acid. Therefore, nitrification can only be accomplished through the interaction of two bacteria.

There are other types of chemosynthetic bacteria in nature, such as sulfur bacteria and iron bacteria.

aerobic bacteria

Sulfur bacteria can oxidize H2S and accumulate sulfur in the body. If H2S is lacking in the environment, the bacteria will oxidize sulfur in the body into sulfuric acid. The chemical reaction formula of this process is as follows:

2h2so2-2h2o2s energy

2S3O 2H2O-2H2SO4 energy

Sulfur bacteria use the energy released by the above two reactions to synthesize organic matter.

Iron bacteria is a kind of bacteria that can oxidize ferrous sulfate. The chemical reaction equation of this process is as follows:

Energy of ferrous sulfate 2h2so4 O2-2fe2 (SO4) 32h2o

Iron bacteria use the energy released by the above reaction to synthesize organic matter.
