Question

explain what microbial growth is?

explain how microbes use Carbon, nitrogen, sulfur and phosphorus?

Answer 1

Microbial growth:

Given the right conditions (food, proper temperature, etc.) microbes can grow very quickly. Depending on the condition, this can be a good thing for people or something bad.
It is important to have knowledge of their growth, so we can predict or control their growth under certain conditions. While the growth of muticelluar organisms is usually measured in terms of an increase in the size of a single organ, microbial growth is measured by an increase in the number of people, either by measuring the increase in the cell number or the increase in the total weight.

-Microbes used in the carbon cycle in small things is part of a larger global carbon cycle. The actions of microbes help release carbon from inanimate sources and make carbon available to living organisms. The carbon which enters the cycle of carbon of microorganisms is carbon dioxide. This form of carbon exists as gas in the air and can be dissolved in water. The atmospheric carbon dioxide can be converted to something that involves the process of photosynthesis.
Carbon derived from sugar carbohydrate molecules is cycled continuously by microorganisms in a series of reactions that form a cycle called tricarboxylic acid (or TCA).
Carbohydrate deterioration contributes to the supply of energy to the microorganism. This process is also known as breathing. In anaerobic environments, microorganisms can circulate carbon compounds to produce the energy of a process known as Fermentation. Carbon dioxide which can be converted to another gas called methane. This occurs in anaerobic environments, such as deep mixed mud, and is made of bacteria called methanogenic bacteria.
Anerobic degradation of carbon is only done by microbes. This shedding is a collaborative effort that involves multiple viruses.

-Nitrogen:

Nitrogen is required by all living things in the formation of organic molecules such as amino acids, nucleic acids and proteins. Small organisms break down proteins into excretions and dead organisms, releasing ammonic ions. These two processes form part of the nitrogen. cannot be used this summer by many organisms until it has been prepared, reduced (combined with hydrogen), to ammonia. Microbes play a key role: Germs fix Nitrogen, converting atmospheric nitrogen into nitrates. The decay bacteria, which convert the decayed nitrogen pollutants into ammonia. Refreshing germs, which convert ammonia into nitrates / nitrites.

-Sulfur:
Like nitrogen and carbon, bacteria can convert sulfur from its highly reactive form to its highly reduced form, The first is the bactericonic purple-green and the sulfur-green that oxidize H2S as an electronic source of cyclic photophosphorylation.
Sulfur-reducing bacteria (SRB) derive their energy by reducing elemental sulfate to hydrogen sulfide. ... These bacteria can be used in industrial processes to produce hydrogen sulfide to obtain iron oxide. Some bacteria can use both sulfur bases and become strong as electron acceptors.  bacteria that reduce sulfate
Reduced sulfur supplements are synthesized by many organisms, including higher animals and higher plants. Other substances can save energy from the oxidation of sulfur. Sulfur is the only source of energy for some lithotrophic bacteria and archaea.

-phosphorous:

phosphate soluble bacteria which are beneficial and are able to synthesize inorganic phosphorus from dissolved components. However, a large proportion of the soluble cooling powders used in the soil as chemical fertilizers are not effective immediately and are not available to plants.
Phosphorus is gradually found in plants over thousands of years, as it gradually gets lost in flight. Low levels of phosphorus in the soil slow down the growth of plants, and delay the growth of microorganisms - as has been shown in studies of soil microbial biomass. Soil microorganisms act as smokers and phosphorus sources found in the biogeochemical cycle.In fact, phosphorus conversion is chemical, biological and micobiological: long-term distribution in the Earth's cycle, however, is driven by tectonic movement during geologic time.
