Study Notes
Microbiology and the Impact of Microbes
- Microbiology is the study of organisms that are too small to be seen without a microscope
- Microbes are found everywhere, including on the human body, and are necessary for the existence of life on Earth
- Microbes are the most abundant form of life on earth, with over 1,000,000,000 bacteria and even more viruses
- The earliest forms of life were microbes, which were able to grow without oxygen, and played a crucial role in the evolution of Earth's atmosphere
- Microbes are important for agriculture as nitrogen-fixing bacteria convert N2 to ammonia, a form of nitrogen that can be used by plants and animals
- Microbes have a significant impact on food production, biotechnology, and the synthesis of commercially valuable chemicals
- Insulin, a hormone used to treat diabetes, is now produced using recombinant DNA technology in bacteria or yeast
- Microbes play a key role in the biodegradation of environmental pollutants and bioremediation, such as cleaning oil spills
- The nature of modern lives increases the likelihood of the emergence and re-emergence of diseases, exacerbated by factors such as civil war and limited access to healthcare resources during the COVID-19 pandemic
- The World Health Organization has reported significant gaps in health outcomes within countries, rooted in differences in social status, income, ethnicity, gender, disability, or sexual orientation
- Antibiotic resistance is a major global public health threat, with several strains of bacteria and fungi resistant to almost every treatment
- Microbes are highly diverse and can be found in extreme environments such as deep sea vents and on the human body, playing a crucial role in ecosystem architecture.
