15 Essential Facts about Bacteria

Bacteria are microscopic, single-celled organisms found in every environment from the oceans, soils, plants, animals, hot springs, and arctic ice to the mountain tops. These fascinating microscopic organisms are found in billions all around the world. They appear in different shapes from spherical to rod-shaped and spiral. They also exist in varying conditions from extreme temperature and pressure and can grow with or without oxygen. Despite being microscopic, they play a vital role in the general ecosystem. They have a significant impact and influence on the health and well-being of human beings. Surprisingly, the human body contains more bacteria cells than human cells. They are responsible for the digestion of food in the body but also cause disease and in some severe incidences lead to death. Some of the diseases caused by bacteria include dysentery, diphtheria, cholera, and typhoid among others. It is, therefore, necessary to understand some of the facts about these fascinating microorganisms yet mighty creatures that dominate much of the world.

Below are 15 essential facts about bacteria.

1. Bacteria can be both Harmful and Beneficial

Bacteria are both beneficial and harmful to the well-being and life at large. However, a larger percentage of bacteria are beneficial while a small percentage are harmful. From the research, we would not exist without them. Some of the benefits of bacteria include the breakdown of nutrients in the digestive system into simpler forms that human bodies can use. However, when the human body is exposed to some harmful bacteria, they attack the human immune system and lead to disease. Some of the diseases caused by harmful bacteria include pneumonia, tuberculosis, and cholera among others.

2. The human body has ten times more Bacterial Cells than Human Cells

It is amazing how these microscopic organisms play a vital role in the well-being of human beings. From research, it has been found that the human body contains ten times more bacteria cells than human cells. The bacteria in the human body exist in form of good bacteria or pathogens which cause diseases including bacterial infections. This is because of their health benefits and the significant role they play in the well-being of animals and plants.

3. Bacteria are Used in Food Technology

Bacteria are very relevant and useful in food production. In the production of cheese, lactic acid bacteria which include lactobacillus and lactococcus, are used together with yeast and mold in the production. Bacteria are also used in the fermentation of food which is beneficial to health and also useful in the preservation of foods. The fermentation process leads to the production of compounds such as lactic acid which have been researched to have anti-inflammatory effects. They a beneficial to the gastrointestinal health of animals and human beings.

4. Bacteria can survive in extreme conditions

Bacteria are unicellular and microscopic organisms that can survive under very extreme conditions. They can survive under very high or low temperatures than any other living organism. However, they do very well in certain conditions which include neutral pH or an environment that is slightly acidic or in warm and moist conditions. Some bacteria, however, thrive very well in conditions such as extreme heat or cold. Other bacteria also do well under very salty conditions or are highly acidic.

5. They are the oldest form of Life

Historians have it that bacteria existed very many years ago drawing back to about 3.5 billion years ago. This was the result of a bacteria fossil that was discovered in the rocks and determined to have existed within that time. They are considered to have been the oldest form of life that existed in the times. This was long before the dinosaurs were thought to exist. They have existed to date because of their ability to survive under extreme conditions and environments.

6. They are found in almost every Environment

The ability of the bacteria to live in conditions makes them live in almost all environments. They exist inside and outside of the body, from the plants, animals, and mountain tops to the depth of the seas and oceans. The fact that they are microscopic and measure a few micrometers in length allows them to live aware unnoticed. They also reproduce in large numbers and exist together in communities of up to millions. The earth is estimated to contain at least 5 nonillion bacteria which make up most of the earth’s biomass.

7. They have different Shapes and Size

The various bacteria come in different sizes and shapes. However, they are classified and categorized into three basic shapes. They exist in shapes which include spherical which are in the shape of a ball called cocci. Other shapes include rod-shaped including Bacillus anthracis and spiral shape bacteria including spirochetes. They are of different shapes but are classified into these three major shapes.

8. They play a vital role in regulating Global Ecosystems

Bacteria play a major role in regulating global ecosystems through their bacterial activity. Bacteria break down dead organisms and waste to release nutrients. This is the process of decomposition where chemicals such as carbon, phosphorous, and nitrogen are released. They also play a significant role in nutrient cycling which is a product of decomposition. They recycle the elements that make up the living system more specifically the process of photosynthesis where organisms take up carbon dioxide and convert it into organic material.

9. Bacteria Reproduce through Binary Fission

One of the factors that make the number of bacteria grow larger, is their ability to reproduce through binary fission. This is the process where a single cell divides into two under favorable conditions. Under suitable conditions, some species of bacteria divide into two after a period of every ten to fifteen minutes. However, according to research, before a cell divides, it begins by replicating the genome so that each daughter contains the exact copy of the DNA. Bacteria can also reproduce through transduction, conjugation, and transformation.

10. Bacteria are used in Industry and Research

 Bacteria have been very useful in the industry and are used in the industry for research. Some of the chemical and pharmaceutical industries use bacteria to produce some of the chemicals. They are also used in certain activities which include cleaning up oil spills, toxic waste, and waste processing. They also serve in biochemical, molecular biology, and genetic research since they grow very fast and are easy to manipulate. Their use is quite extensive and goes a long way in the production of antibiotics and other products.

11. They can survive without Food for Over 1000 days

Bacteria can survive not only under extreme conditions in harsh environments but can also go without food for a duration of over one thousand days. This was according to research conducted by scientists who starved different groups of bacteria for over two and half years and most of them survived. One of their unique characteristics is their ability to deliberately stop meddling with their inside mechanism when they run out of resources. This mechanism allows them to evolve and survive under harsh conditions. They undergo a condition referred to as active evolution.

12. Most bacteria are Motile

Many of the bacteria can move by themselves while others are not. However, motile bacteria use several mechanisms to move. They use flagella to generate different kinds of movements. They can either move forward or tumble which allows them to make a three-dimensional random movement. There are three major ways in which the bacteria move around and this includes by gliding motility, corkscrew motility, or by swimming.

13. Bacteria Communicate Using Electrical Signal

It is amazing how these fascinating creatures communicate with each other through the use of electric signals. In this act, single-celled bacteria can act similarly to multicellular organisms. These micro-organisms work together like a microbial colony while they are in a colony of billions. This behavior is more common in biofilms which build up in rocks in rivers or nanotubes to bridge between different cells to exchange proteins, plasmids, and small molecules.

14. Some Bacteria are Predators

Some species of bacteria are predators that kill and feed on other microorganisms. They are referred to as predatory bacteria which include Myxococcus Xanthus and other bacteria. These bacteria form swam of cells then kill any bacteria they encounter and digest them. Other bacteria attack their prey to digest them and absorb the nutrients from the prey. They also use the mechanism of multiplying inside the cytosol.

15. They can be used to Store information

Research has shown that bacteria can be used to store messages and later retrieve them. However, this is applicable within the living cells of bacteria. Scientists were searching for somewhere to store important information in case of a nuclear catastrophe. They chose to use the bacteria Deinococcus radiodurans since they can survive under high temperatures, UV light, radiation, or drying out. After the research, it was discovered that they are capable of storing a piece of information in cases of a nuclear catastrophe.

Bacteria are microorganisms that play a vital role in the existence of the human race, plants, and animals altogether. They are microscopic and numerous yet with so many benefits. However, some species of bacteria are harmful and can cause severe effects that lead to death.
