Bioremediation is the process of using microbial metabolism to degrade or remove toxic chemicals and pollutants from contaminated environments, such as water and soil.

The field of Microbiology impacts society in many positive ways including the discovery and development of antimicrobials,  the use of bioremediation to clean the environment, phage therapy, food production, vaccine development, and genetic engineering.

Microbiology Contributions and it's Impact on Society

Prokaryotes are vital to shaping and sustaining the global biosphere. Some prokaryotic species generate substantial amounts of oxygen, others convert atmospheric nitrogen into usable forms for plants and animals, and some reside in the human body where they produce essential substances and protect against pathogens.

Microbiology covers the scope and sequence requirements for a single-semester microbiology course for non-majors. The book presents the core concepts of microbiology with a focus on applications for careers in allied health. The pedagogical features of the text make the material interesting and accessible while maintaining the career-application focus and scientific rigor inherent in the subject matter. Microbiology’s art program enhances students’ understanding of concepts through clear and effective illustrations, diagrams, and photographs.

Microbiology is produced through a collaborative publishing agreement between OpenStax and the American Society for Microbiology Press. The book aligns with the curriculum guidelines of the American Society for Microbiology.

Microbiology led to vaccine development that provide cures to a variety of viral pathogens. The use of vaccine development has improved so well in which several of vaccines have gotten approved such as the COVID-19 vaccine and having the ability to target different pathogens all at once. 

Vaccine Development

Microbiology had an impact on society through its contribution of genetic engineering which involves the use of recombinant DNA technology within a laboratory settin creating recombinant DNA molecules that have new combinations of genetic material which paved the way for DNA technology advances in medicine.

Genetic engineering

Antimicrobials have been around for centuries and are known one of the main methods in modern society. Antimicrobial can be found in plants and molds which can be used to treat a variety of diseases for medical purposes. The development of antimicrobials led to antimicrobial drugs such as penicillin. 

Development of Antimicrobials

Bioremediation

Microbiology impacted society through food and beverage production such as beer, wine, bread, yogurt, cheese, and pickled vegetables through the use of fermentation to enhance the taste and preserve the goods longer. 

Food and Beverage Production

Phage therapy is a clinical procedure that uses bacteria-killing viruses (bacteriophages) to treat bacterial infections. First introduced in 1915 by Frederick Twort, this therapy was largely abandoned after the discovery of antibiotics, but interest has re-emerged due to the increase in antibiotic-resistant bacteria.

Phage Therapy

Prokaryotes are vital to soil formation and stabilization. They decompose organic matter and form biofilms. In the rhizosphere, soil bacteria metabolize organic substances secreted by plant roots (such as acids and carbohydrates) and return the metabolic byproducts to the soil, forming nutrient-rich humus that increases soil fertility.

Role of Prokaryotes in Soil Fertility

Soil ecosystems host an immense concentration of microscopic life. A single gram of soil can contain up to 10 billion microorganisms, most of which are prokaryotes, representing approximately 1,000 different species.

Abundance and Diversity of Soil Microorganisms

Nitrogen fixation is the conversion of atmospheric nitrogen into ammonia, a nitrogenous compound that plants can use to synthesize essential biomolecules.

Nitrogen Fixation

Prokaryotes act as key players in climate change when rising polar temperatures cause permafrost to thaw. As the frozen soil melts, prokaryotes metabolize the trapped carbon, releasing massive amounts of carbon dioxide and methane into the atmosphere and contributing to the greenhouse effect.

Role of Prokaryotes in Climate Change

Carbon fixation is the biological process by which microorganisms capture and convert inorganic carbon sources, such as carbon dioxide, into organic compounds.
