Microbiology also discusses the efficient use of a few microbes for industrial applications.

Microbes are found in soil, water, and even inside humans, plants, and animals. They play a significant role in biogeochemical cycling. There is a lot of application of microbiology in daily life. In this article, we will discuss how is microbiology used in everyday life.

Real-life Applications of Microbiology

Real-Life Applications of Microbiology

Antonie van Leeuwenhoek is the father of microbiology. He observed and experimented with different microscopic organisms in 1670 by using simple microscopes. Real-life applications of microbiology include food production, biodegradation, the manufacturing process of commercial goods, and most importantly genetic engineering. Microbiology has progressed in different areas like medicine, pharmacy, research, dairy farming, agriculture, water management, and chemical technology over the years.

How is Microbiology Used in the Food Industry?

• Certain bacteria i.e. the Lactobacillus, Lactococcus, and Leuconostoc families are used to ferment dairy products.
• Vinegar is produced when the Acetobacter genus bacteria convert ethyl alcohol into acetic acid.
• Lactic acid is a colorless and odorless liquid with a sour taste. It is generated by microaerophilic Lactobacillus bacteria. It is commonly used in the flavoring of beverages.
• In the process of winemaking, yeasts play a major role. These yeasts convert natural sugars into alcohol and carbon dioxide.
• Saccharomyces cerevisiae is a yeast that is used for fermentation.

How is Microbiology Used in the Health Industry?

• Vaccines are created with weakened or killed forms of bacteria, their toxins, or surface proteins.
• They also contain a substance that mimics disease-causing bacteria.
• This helps the immune system recognize and remember the bacteria for future encounters.
• Antibiotics are manufactured in factories using a fermentation method.
• Microorganisms are grown in large containers with a liquid growth medium.
• Antibiotics are considered byproducts of microorganisms.
• Microorganisms are utilized in the health industry to produce enzymes, vitamins, amino acids, steroids, and other substances.

How is Microbiology Used in the Agricultural Industry?

• Various small organisms like rhizobium bacteria and mycorrhiza fungi, are very important for helping plants grow.
• They form helpful relationships with plants like the relation between legumes and rhizobium, and the partnerships with mycorrhizal fungi.
• Microorganisms are essential for processes like fixing nitrogen, turning organic matter into ammonia, converting ammonia into nitrates, and changing nitrates back into nitrogen gas.
• They assist in converting nitrogen from the air into forms that plants can use, recycling nitrogen from organic matter, and maintaining a balanced nitrogen cycle in soil ecosystems.

How is Microbiology Used in the Biofuel Industry?

• Microbes like yeast, are used to convert sugars into ethanol for biofuel production.
• Saccharomyces cerevisiae is commonly used in industries for this biofuel production.
• Biogas can be generated through a defined mix of microbes in fermenters or through the cooperation of specific microorganisms capable of breaking down acetate and consuming hydrogen from cow dung or wastewater sludge.
• Hydrogen is recognized as a byproduct of photosynthesis or the end product of fermentation in various microbes.
• Certain microorganisms like cyanobacteria and green algae can produce biohydrogen during photosynthesis.
• Cyanobacteria and green algae are examples of microorganisms capable of photosynthesis.
• These microorganisms produce hydrogen as a byproduct during the photosynthesis process.

How is Microbiology Used in the Mining Industry?

• Acidithiobacillus ferrooxidans is used more and more to get valuable metals, especially copper, from low-quality rocks that can not be processed using normal methods.
• Bacteria are also used to get other metals like uranium and gold. The ways might be a bit different, but they all involve changing a hard-to-dissolve stuff into an easy-to-dissolve one.

How is Microbiology Used in the Water Industry?

• Biological wastewater treatment uses different bacteria and other tiny organisms to clean dirty water.
• Filters get rid of bigger protozoans, while chemicals or UV light kill bacteria and other harmful organisms.
• The water self-purification principle is applied here, where microorganisms like bacteria, protozoa, and tiny animals consume organic stuff in water to break them down and remove them.

How is Microbiology Used in the Cosmetic Industry?

• Fatty acids, enzymes, peptides, vitamins, lipopolysaccharides, and pigments in microbes are good for cosmetics.
• Microbes make special compounds like ceramides, mycosporine-like amino acids, carotenoids, and omega-3, 6, and 9 fatty acids, which are used in the cosmetics industry.
