Bacillus (Bacillus, plural. Bacilli)

Bacilli (Bacillus) are a group of bacteria that are rod-shaped and highly resistant to external influences. They are one of the most common microorganisms in nature and play an important role in various biochemical processes.

Bacilli are gram-positive bacteria, which means they have a thick cell wall that protects them from external influences. They also have a polar capsule that serves to protect the cell from phages (viruses that infect bacteria).

Bacilli can be both pathogenic and beneficial to humans. Some types of bacilli are used in the food industry to produce fermented milk products such as yogurt and kefir. Other types of bacilli can cause various diseases, including tuberculosis, anthrax and botulism.

One of the most common types of bacilli is Bacillus subtilis. It is used in the production of antibiotics and other drugs. There are also many other types of bacilli, each of which has its own unique properties and applications in various fields of science and industry.

Overall, bacilli are an important element in the Earth's ecosystem and are the subject of study for scientists around the world. Their study helps to understand the mechanisms of interaction between microorganisms and the environment, as well as to develop new methods to combat bacterial infections and improve the quality of life of people.

Bacilli are a group of rod-shaped bacteria that are rod-shaped and can be found in various environments such as soil, water, air and others. They are among the most abundant bacteria on Earth and play an important role in various processes such as the decomposition of organic matter, fermentation and the synthesis of antibiotics.

The bacilli range from 2 to 10 micrometers in length and 0.2 to 0.5 micrometers in width. They can be dyed in various colors such as white, yellow, red and blue, depending on their pigment content.

One of the best known bacilli is Bacillus subtilis, which produces subtilisin, an enzyme used in the production of detergents and other products. The bacilli can also produce antibiotics, such as bacitracin, which is used in medicine to treat infections.

However, bacilli can also be harmful to humans and animals, causing various diseases such as tuberculosis and botulism. Therefore, it is necessary to maintain hygiene and avoid contact with contaminated environments to avoid infection.

In general, bacilli are important microorganisms in nature and have wide industrial and medical applications. However, their improper use can lead to serious consequences for human health and the environment.

Bacillus

Bacilli are rod-shaped bacteria, which are representatives of gram-positive microorganisms that are highly resistant to environmental conditions and have high reproductive abilities. Representatives of this genus occupy an important place among the bacteria of the human body, are capable of decomposing various compounds of organic origin and play an irreplaceable role in nature (they are producers of some antibiotics, etc.).

The main representatives of the genus of bacilli: Pseudomonas aeruginosa (Sinegrous glaezia), nodule bacilli (Sitophis agriopalo-carpae), some species of Actinomyces (Actinomyces toxorum, actinomyces equorum), enterococci (Ectereococcus faecalis).

All bacilli are gram-positive, nonmotile. Most do not form spores. Only 8 types of bacilli have spores, forming a capsule (group C. perfringens, C perfringens): the capsule forms spores, giving them a dense shell that protects the microbe from unfavorable environmental conditions. Under the influence of atmospheric oxygen inside the capsule, spores form endospores, which are protected in sporangia on the cell wall. After being in unfavorable conditions, endospores form colonies of voracious, mobile, capsule-free, large spore-forming bacteria - clostridia. The ability to form spores gives the bacilli greater viability - the ability to survive for a long time.

As the colonies grow, their color gradually changes and becomes similar to spores, which is why they are called “spores.”
