Imagine you are sitting at your bench carefully preparing samples as all around you scientists bustle back and forth with racks of test tubes and stacks of agar plates. You are a microbiologist and your lab is operating in high gear. Two days ago, a tanker truck hauling liquid waste from a nearby hog operation overturned on Reservoir Bridge, spilling its contents into your city's drinking water. As part of a team of microbiologists specializing in environmental emergency response, you were immediately called in to analyze the extent of contamination and the threat this spill poses to public health.
As a microbiologist with a specialty in environmental pathogens, you know how critical it is to quickly and accurately identify what has been spilled into the water supply. The reservoir's water is treated before being distributed to city residents, but without knowing what is in the water, there is no way of knowing if it is being removed at the treatment plant. You have spent the last two days analyzing samples from the reservoir and tanker, preparing dozens of cultures, and using DNA-based molecular techniques to identify potential pathogens.
Once you have established the presence and extent of contamination, you and your team can begin to develop ways to remove it, for example adding additional filters to the treatment plant, disinfecting the water with UV rays, or possibly adding other micro-organisms to the water supply that kill pathogens without posing a threat to the health of humans or the reservoir's aquatic communities. With your team's hard work and expertise, the city's water supply will be clean and back to normal in only a few more days.
Duties vary significantly from job to job, but the following list includes typical job duties one might encounter as a microbiologist:

There are a number of places microbiologists can find employment. They include:
If you are a high school student considering a career as a microbiologist, you should have strong marks or an interest in:
In most cases, the minimum education requirement to work as a microbiologist is a university undergraduate degree. If you are a post-secondary student considering a career as a microbiologist, the following programs are most applicable:
Although in most cases it is not necessary to become certified in order to work as a microbiologist, some practitioners choose to apply for professional status, for example Professional Biologist. The requirements for certification and professional status vary among provinces.
Chantal Bouchard's current mission in life sounds too good to be true-she is working to develop a new herbicide that is biodegradable, environmentally friendly and created from recycled waste. If that is not enough, it has to be affordable for farmers and profitable for her employer. That such a herbicide might be possible says something about the vital role of science in the service of the environment.
What led Chantal into a career in microbiology? She credits her love of sciences, biology and math as a teenager. Summer science camps in Quebec fired her interest even more and led to undergraduate studies in biology (with a major in ecology) and a master's degree in plant physiology. Among the skills she considers important in her work, she rates interpersonal skills very high. "In dealing with farmers, you have to be prepared to make requests in the most diplomatic way possible.
To test new products, we sometimes have to make some strange requests." Chantal's formula for success is simple-"patience, patience, patience. And imagination and perseverance in developing new techniques and procedures." Plus, "You must love what you are doing."
