Microbiology has gained popularity in recent years, increasing the number of students interested in pursuing a career in microbiology. A microbiologist is a person who specializes in the field of microbiology. Microbiologists are scientists who play an important role in studying organisms and infectious agents that cannot be seen with the naked eye. They also investigate the interactions of microorganisms with humans and other organisms that exist and have an impact on our lives. Microbiologists also test food to see if it is safe, develop green technologies, and study the role of microbes in the environment.
