The information gained by microbiologists can be applied to many medicinal and commercial endeavors.
- Explain applied microbiology
- Using knowledge gained by microbiologists studying microbes, several fields of applied microbiology have formed.
- While food and medicinal applications are a big portion of applied microbiology, the study of microbes has lead to entire commercial industries which affect almost all aspects of human life.
- There are a myriad of practical applications that microbiology contributes to, including several parts of food production and medicinal applications.
- rhizosphere: The soil region subject to the influence of plant roots and their associated microorganisms.
- biotechnology: The use of living organisms (especially microorganisms) in industrial, agricultural, medical, and other technological applications.
- pathogenic: Able to cause harmful disease.
Microbiology is the study of microbes, which affect almost every aspect of life on the earth. In addition, there are huge commercial and medicinal benefits in understanding microbes. The application of this understanding is known as applied microbiology. There are many different types of applied microbiology which can be briefly defined as follows:
Medical microbiology is the study of the pathogenic microbes and the role of microbes in human illness. This includes the study of microbial pathogenesis and epidemiology and is related to the study of disease pathology and immunology.
The study of microorganisms that are related to the production of antibiotics, enzymes, vitamins, vaccines, and other pharmaceutical products. Pharmaceutical microbiology also studies the causes of pharmaceutical contamination and spoil.
The exploitation of microbes for use in industrial processes. Examples include industrial fermentation and waste-water treatment. Closely linked to the biotechnology industry. This field also includes brewing, an important application of microbiology.
The manipulation of microorganisms at the genetic and molecular level to generate useful products.
Food Microbiology and Dairy Microbiology
The study of microorganisms causing food spoilage and food-borne illness. Microorganisms can also produce foods, for example by fermentation.
The study of agriculturally relevant microorganisms. This field can be further classified into the following subfields:
- Plant microbiology and plant pathology – The study of the interactions between microorganisms and plants and plant pathogens.
- Soil microbiology – The study of those microorganisms that are found in soil.
- Veterinary microbiology – The study of the role in microbes in veterinary medicine or animal taxonomy.
The study of the function and diversity of microbes in their natural environments. This involves the characterization of key bacterial habitats such as the rhizosphere and phyllosphere, soil and groundwater ecosystems, open oceans or extreme environments (extremophiles). This field includes other branches of microbiology such as: microbial ecology (the role of microbes in ecosystems), geomicrobiology (interactions between microbes and their physical and chemical surroundings), microbial diversity, water microbiology (the study of those microorganisms that are found in water), aeromicrobiology (the study of airborne microorganisms) and epidemiology (the study of the incidence, spread, and control of disease). Bioremediation involves the application of microbial processes to remove pollutants from the environment.
This is by no means an exhaustive list of the different types of applied microbiology, but gives an indication of the expansive variety of the field and some of the benefits these studies entail.
