As bacteria feed on? The structure and vital activity of bacteria

Bacteria – protozoa. Most often they have only one cell. In nature there are both beneficial and harmful to humans and the environment micro-organisms. One way or another, they all share a primitive structure and of small size. After reading the article, you can figure out how bacteria eat, reproduce, and breathe.

General information about bacteria

Bacteria – netcarta prokaryotic microorganisms. Today there are more than five thousand of its members. Scientists say that actually the microscopic creatures are much more. Bacteriology-the science that studies microorganisms.

The average is 0.5-5 microns. They are divided into two groups – unicellular and multicellular. First carry out all the processes that are inherent in a living organism. It is worth noting that most bacteria are mobile.

The Term "bacteria" as an independent unit originated in the late 70-ies of the last century. He was formerly a synonym for prokaryotes. The studies in 1977 found that they were divided into two groups. One of them used the term "bacterium".

The Process of respiration in bacteria

To reproduce the process of respiration of many microorganisms, like people, need oxygen. Such representatives are called aerobes. However, there are those bacteria protozoa, which do not need air. The oxygen for these microscopic creatures – a kind of poison. Their scientific name – anaerobes.

They live at the top and loose layers of soil, in food and water. Make their livelihoods at great depths in the soil, reservoirs, and also directly in the Il. It should be noted that the respiration of aerobic bacteria is impossible where there are anaerobes.

It's No secret that microorganisms can cause fermentation. Breath bacteria is a kind of agent provocateur of the process. The most striking example – yeast. As a result of their fermentation produces carbon dioxide and water.

Nutrition protozoa. Parasitism

As the bacteria feed on and what is parasitism? These questions are often interested not only biologists, but just curious people. The answers you can find in our article.

The Microorganisms that feed on organic matter, are divided into two groups – saprotrophs and parasites. First eat rotten leftover food, and the second live at the expense of other animals. Today, parasitism – this is a fairly common phenomenon. It occurs as the microorganisms and humans and also in animals. Often it is the parasitism can cause serious illness.

It is Known that microorganisms there are two ways to supply. Heterotrophic organisms – these are microscopic creatures that are used for its development ready organic matter. The second group includes autotrophs-organisms that provide themselves with food. This cyanobacteria, iron bacteria and sulfur bacteria. The first play an important role in the process of photosynthesis. That is cyanobacteria created from inorganic substances organic.

Heterotrophic organisms can be divided into three groups: parasites, saprophytes and symbionts. Usually parasitic bacteria live and act in the body of animals, birds, fish or people. They can also live on the surface of the skin. Bacteria often can parasitize on plants. It should be noted that heterotrophic bacteria are unable to carry out their livelihoods on a healthy flora. This can happen only if on its surface there are fresh wounds. Often become infected seeds and bulbs. In this case, the infection is transmitted vegetatively. The cause of bacterial disease may be a rain or artificial watering. Most often the infection is spread by insects, mites and birds. In the human body parasitism can cause tuberculosis, influenza, diarrhoea, cholera and plague.

Saprophytes and symbionts

Saprophytes – it is the bacteria that feed on dead organic matter. They extract nutrients from non-living material, and then leave there their enzymes. They learn of the solute.

The Prototype – it is bacteria that not only live together with other organisms, but also bring them great benefit. For example, these microscopic creatures live in the tubers of legumes. They absorb nitrogen, which is a fertilizer for plants. In humans and animal symbionts are also present. They allow to efficiently process the food and provide invaluable health vitamins.

Useful properties of bacteria

Surprisingly, the total weight of the microorganisms that populate our bodies is about two pounds. The beneficial bacteria that inhabit the body or other living entity, are called microbiota. Each organism has over a million. Microbiota is responsible for good health. Beneficial bacteria protect the body from pathogens.

The main distribution area of the microbiota – the intestines. Beneficial bacteria create an acidic environment, which do not carry pathogens.

Natural protection

In the properties of bacteria in the respiratory tract of man and on the surface of his skin, is to protect their habitat. The most dangerous pathogens that attack these zones are Streptococcus, Staphylococcus and micrococci.

Over the past few centuries, the natural protection of human skin has undergone many significant changes. This is due to the fact that society has moved from a close relationship with nature to be in constant contact with chemicals. Scientists have proved that the set of microbiota, which is on the surface of the skin today, differs significantly from that which existed previously.

Recovery of the microcosm

It is Known that the microbiota of the organism fast enough updated. Food bacteria depends on the diet of their host. The most dangerous for microorganisms foods that contain antibiotics, preservatives and artificial dyes. These substances destroy the natural microcosm of man. This can later be linked to a variety of health problems.

It is Quite important to understand that the microcosm requires careful attention. Highly recommend periodically to restore the microbiota to prevent a number of diseases. It is necessary to use a course of probiotics. To maintain its own microcosm'll need to eat more vegetables to keep your weight and natural Breakfast cereal.

Many people wonder how they feed the bacteria that are in our body. We found that the beneficial micro-organisms consume the same as their carrier. It is for this reason to maintain a strong immune system we first need to reconsider your diet.

Enzymes to improve the General status

Perhaps each of us is familiar with the situation, when after eating significantly worsens the General condition. In this case, it is invaluable enzymes and bacteria. Where can I find them and how they act on the human body?

Many people say that after the festive excesses, they feel bad for several days. They complain of goiter, weakness and lack of appetite. All these symptoms indicate that harmful bacteria are trying to push healthy. To cope with the process and restore good health, it is necessary to include in the diet foods that are composed of enzymes of bacteria. These include curd, cheese, kefir, yogurt, fermented baked milk and other dairy food. Experts also recommend taking medicines that contain probiotics. Before starting treatment, it is strongly recommended to consult with your doctor.

Sensational discovery. Bacteria that eat plastic

The Structure and vital activity of bacteria is of interest to biologists from around the world. They believe that microorganisms are not as primitive as it seems. This is confirmed by a discovery made by a group of Chinese biochemists and microbiologists. Two years ago they found a bacteria that can eat plastic. According to scientists, this will allow you to save the planet from ecological disaster.

The Discovery was made quite by accident. The team leader notes that at his house there is always a mild disorder. One day he noticed that in a plastic bag with the remains of cereals there is a large number of small larvae, which eat disposable packaging. This case gave the researcher the idea that it can help to save the planet from global pollution.

After conducting a series of experiments, the team leader learned that the larvae not only eat the plastic and polyethylene, but ...
