How do the poor people of the local communities live?

Sulfur water places a sulfur atom in a new form, which is easily oxidized due to the high amount of energy.

Due to the presence of active enzyme systems, this energy can be utilized as a result of ATP synthesis.

And the energy of ATP, in its turn, can be converted into carbon dioxide and the synthesis of “primary” living substances (carbohydrates) from carbon dioxide.

Necessary enzyme systems are present in many types of bacteria.

Like green weeds, the smell is caused by autotrophic organisms that independently create organic matter from inorganic matter.

Prote, as the plants lie up to the group of phototrophs, then.

Acid-free (anaerobic) diet It is important in nature for bacteria to extract energy from inorganic substances due to the presence of sourness.

Denitrifying bacteria reduce nitrates to gas-like nitrogen and nitrous oxide: 10H + 2H+ + 2NO3- N2 + 6H2O + ATP In the presence of these bacteria, instead of nitrogen in the atmosphere, the growth rate has changed It has grown and the biomass on Earth has collapsed.

Molecular jelly, which appeared in the Earth’s atmosphere, acting as a strong oxidizer.

One of the first began to involve the aerobic metabolism of bacteria, which oxidize inorganic substances to nitrogen, syrup, and liquid.

Nitrifying bacteria oxidize ammonia to nitrates.

NH4+ nitrite bacteria NO2- nitrate bacteria NO3- Regardless of the presence of acid in the oxidation reactions of ammonia, the energy balance of the bacteria that nitrify appears to be very low.

Syrchan bacteria – naturally oxidize sulfur, which is formed at the end of the sulfate reaction: S2- + 2O2 SO42- or S2- + SO2 + 2H2O SO42- + 4H+ Abundantly sulfur bacteria live in extreme hot waters sparkling volcanic vents.

They can reach temperatures up to 750C and then oxidize the sulfur or sulfuric water to sulfuric acid.

These bacteria are called thermophiles.

Zalizobacteria – bacteria oxidize bivalent to trivalent zest.

Completely oxidize ammonia, which is formed during the decomposition of organic excess nitrous acid, and then nitric acid.

2NH3 + 3O2 = 2HNO2 +2H2O+663 kJ 2 HNO2 + O2 = 2HNO3 + 142 kJ Nitric acid, reacting with mineral compounds, dissolves nitrates in the soil, which are readily absorbed by plants. Nitrifying bacteria.

Oxidize the sulfur water and accumulate the sulfur in your skin: 2 H2S + O2 = 2 H2O + 2 S + 272 kJ If the sulfur water does not run out, prevent bacteria from oxidizing the sulfur to sulfuric acid: 2 S + 3 O2 + 2 H2O = 2H 2SO4 + 6

Oxidize bivalent zalizo to trivalent 4 FeCO3 + O2 + 6 H2O = 4 Fe(OH)3 + 4 CO2 + 324 kJ Zalizobacteria

Vicoristic energy that is seen during the oxidation of molecular water 2H2O + O2 = 2 H2O + 235 kJ

Nitrifying bacteria contribute to the circulation of nitrogen in the biosphere. Ecological role of chemosynthesis

By soothing sulfuric acid, it is necessary to remove the ruin and vitrification of the Georgian rocks;

Ruin rocks and metal spores Vilug ore and sirchani ancestors Purification of industrial wastewater

Solution of Fe(OH)3, which is used to cure swamp salivary ore Zalizobacteria

presentation photosynthesis and chemosynthesis

Presentation on biology for 9th grade students.

Line of V. Pasichnik.

This presentation examines the peculiarities of the processes of photosynthesis and chemosynthesis and their role.

"Photosynthesis. Chemosynthesis"

Lesson summary: learn the peculiarities of metabolism of autotrophic organisms in relation to the process of photosynthesis. Task: lighting - reveal the peculiarities of the process of photosynthesis, the essence of the light and dark phases.

Slide 3

And here, where photosynthesis is slow, where producing plants do not grow, like the first lange of the grub lancet.

The shallow water in which the inhabitants of the Garden of Eden swam (the name itself was given to the open field) is already saturated with the spring water.

Such people are with the black "dims" that there are among them, they are seen at the same time under the names of the black kurts.

Vikorista rely on the energy of honeycomb light (photosynthesis) for the synthesis of ATP, then the bacteria live for chemosynthesis and are called chemotrophs.

Denitrifying bacteria produce nitrates to gas-like nitrogen and nitrous oxide: 10H + 2H+ + 2NO3-  N2 + 6H2O + ATP The presence of these bacteria instead of nitrogen in the atmosphere has changed The growth of trees and biomass on Earth has slowed down.

Sulfate-reducing bacteria create water from sulfate: 8H + SO42-  H2S + 2H2O + 2OH- + ATP Water for this reaction of bacteria is taken from glycolytic products.

The energy that is stored in this process is used for the synthesis of organic compounds.

These bacteria are found in the deep waters (for example, near the Black Sea at a depth of over 200 m).

Most genera of sours are biogenic sours.

Anaerobic chemoautotrophy

Nitrifying bacteria oxidize ammonia to nitrates.

Molecular jelly, which appeared in the Earth’s atmosphere, acting as a strong oxidizer.

Nitrifying bacteria oxidize ammonia to nitrates.

NH4+ nitrifying bacteria NO2- nitrifying bacteria NO3- Regardless of the presence of acid in the oxidation reactions of ammonia, the energy balance of nitrifying bacteria was very low.
Salizobacteria (Geobacter, Gallionella) oxidize bivalent saliva to trivalent.
Syrcobacteria (Desulfuromonas, Desulfobacter, Beggiatoa) oxidize sulfuric acid to molecular sulfur or salts of sulfuric acid.
Nitrifying bacteria (Nitrobacteraceae, Nitrosomonas, Nitrosococcus) oxidize ammonia, which is formed during the decay of organic substances, nitrous and nitric acids, which interact with soil minerals, nitrites and nitrates create.
Thion bacteria (Thiobacillus, Acidithiobacillus) regularly oxidize thiosulfates, sulfites, sulfides and molecular sulphur to sulfuric acid (often due to a significant decrease in pH), the oxidation process is divided into such sulfur bacterium (preserve that thionic bacteria are not added).
These are representatives of thion bacteria and extreme acidophiles (able to survive and reproduce at low pH levels up to 2), which vitrimate high concentrations of important metals and oxidize metals and divalents not climbed (Acidithiobacillus ferrooxidans) and heavy.

Water bacteria (Hydrogenophilus) naturally oxidize molecular water and die thermophiles (grow at temperatures of 50 °C)
Expanded environmental functions
Chemosynthetic organisms (for example, sulfur bacteria) can live in the oceans at great depths, in these places, where the earth's crust breaks up, the water comes out in the wild.
Of course, light quanta cannot penetrate water to a depth of about 3-4 kilometers (at such depths there are most rift zones in the ocean).
According to current estimates, the biomass of the “underground biosphere,” which is located beneath the seabed and includes a chemosynthetic anaerobic methane-oxidizing archaebacterium, may exceed the biomass of the upper biosphere.
