What is microbiology?
Microbiology is the study of all living organisms that are too small to be visible with the naked eye. These living organisms are known as microbes. Examples of microbes include bacteria, archaea, viruses, fungi, prions, protozoa, and algae. These microbes have major roles like nutrient recycling, biodegradation, climate change, food spoilage, the cause and control of the disease, and biotechnology. Some of the benefits of these microbes include making life-saving drugs, the manufacture of biofuels, cleaning up pollution, and the processing of foods and drinks.
Branches of microbiology.
Bacteriology.
The study of bacteria.
Immunology.
This is the study of the immune system.
Mycology.
This is the study of fungi.
Nematology.
This is the study of nematodes.
Parasitology.
The study of parasites.
Phycology.
This is the study of algae.
Protozoology.
This is the study of protozoa, single-celled organisms like amoebae.
Virology.
This is the study of viruses.
Types of Microorganisms
The major types of microorganism include:
- Bacteria
- Archaea
- Fungi (yeasts and molds)
- Algae
- Protozoa, and viruses
Applications of microbiology.
- It provides information about different types of microorganisms enabling us to understand their structure and functions, their classifications, and to derive phylogenetic relationships and to understand the origin of life itself.
- Microorganisms are used as food. They are also being used as single-cell protein in the form of yeasts, bacteria, cyanobacteria, fungi as human food or animal feed. Moreover, microbial products are also used as animal feed.
- Microorganisms are used in the production of a large number of, fermented foods such as leavened bread, sourdough bread, fermented milk products, and flavors. Examples of fermented milk products include: yogurt, cheese and etc.
- They are used in making important fermented vegetables like sauerkraut (from cabbage) and Kimchi.
- Fermented meats and fermented fish are used in different parts of the world due to their increased storage time, otherwise the meats and fish are highly perishable.
- Microbiology is used in making beer, vinegar, tempeh, soya sauce, rice wine which are fermented products.
- Microbiology is used in the preservation of food by heat processing, by pasteurization and appertization, by calculating thermal death values, prevention of spoilage of canned foods, aspectic packaging, irradiation, UV radiation, ionizing radiation, high-pressure processing, that is, pascalization, low-temperature storage, chemical preservatives.
- Microorganisms are the causative agents of a large number of microbial diseases.
- A large number of products of microbial metabolism after microbial processing of raw materials are produced on an industrial scale. Therefore, microbiology largely influences Industrial microbiology.
- Some substrates can be used as a source of energy as biogas from methanogenic microorganisms.
- Degradation of cellulose and lignin. For example, Trichoderina reesei can be used to degrade cellulose since it produces extracellular cellulase.
- Mining and extraction of metals. For example, Thiobacillus ferrooxidans and combination of Leptospirillum ferroxidans and Thiobacillus organoparpus can be used to degrade pyrite (FeS2) and chalcopyrite (CuFeS2).
- Recombinant DNA and genetic recombination.
- Hybridoma and preparation of monoclonal antibodies: Hybridoma is a cell made by fusing an antibody-producing B-cell with a cancer cell. The resulting hybrid myeloma or hybridoma cells have properties of both parent cells immortality and the ability to secrete large amounts of a single specific type of antibody. This was discovered by Kohler.
- Harvesting DNA biotechnology for public health engineering programmes.
- Microbial technology of nitrogen fixation exploiting symbiotic microorganisms in association with lower or higher plants and a symbiotic or nonsymbiotic.
- Making faster and smarter computers.
