Introduction to microbiology, separation and identification of microorganisms, areas where microbiology is used

Microbiology includes single-celled organisms called microorganisms, viruses, and mushrooms

Microorganisms are the oldest living organisms, playing an important role in the biochemical cycle and can live in places that are unsuitable for other organisms.

(Also, other organisms need microbes.)

There are two reasons to study microorganisms.

 

1. It is a model to study the cellular processes within single cells and multicellular cells by understanding basic life phenomena and understanding life phenomena.

2. It is the application of knowledge for the benefit of humanity. It plays an important role in medicine, agriculture and industry, and will become an even more important role in the future.

Microorganisms are easily classified into three categories.

1. Prokaryotic... bacteria

2. Eukaryota... Fungi, mold, etc.

3. (virus)

Microscopic microscope used to view microorganisms.

Scanning electron microscope (SEM) and

There is a transmission electron microscopy (TEM).

The main difference between a scanning electron microscope and a transmission electron microscope is the observation part

A scanning electron microscope is a microscope that checks the outside, and a transmission electron microscope is a microscope that identifies the inside.

In various industries of microbes, the role played a very large role, and it plays a role.

Alexander Fleming, who developed and discovered penicillin

Antibiotic is the biggest representative work in medicine.

Antibiotics are getting stronger from penicillin to methicillin and vancoin.

However, since microorganisms also evolve and have resistance, super bacteria are expressed and evolve into pathogenic bacteria that can cause septicemia (Sepsis).

Since super bacteria are mostly infected in hospitals, hospitals should take appropriate measures.

In agriculture, animals used for livestock, such as cattle, pigs, and dogs, are given antibiotics to increase livestock efficiency.

However, as said in medicine, because microorganisms are resistant, animals can be resistant, and can be made to have secondary resistance through meat, etc. that humans eat.

The representative use of microorganisms in the industry is the use of ocher.

I think this is Finland during World War II.

Finland used Nazi Germany during World War II to defeat Soviet interference.

When the prewar of World War II leaned towards the Allied Powers, Finland ended its alliance with the Nazis and drove out Nazi Germany.

  Loess is used as a solution to red tide and green algae phenomena because it contains a lot of antibiotics because it has many actinomycetes (which cause soil odor).
