Microorganisms have a vital and important role in food science. Microorganisms are responsible for digesting food that the body can't on its own, such as the complex sugars found in grains, fruits and vegetables. As part of the digestive process, the microbes break down nutrients to extract calories that can be stored as fat. Microbial processes are responsible for the production of many foods that we enjoy on a daily basis including cheese, yogurt, beer, wine and even coffee. Microbes can also cause spoilage of our food and even illness in ourselves and agricultural commodities. The Ponder laboratory investigates microbial interactions of native microbes with its host and other microbes, especially human pathogens. We are interested in identifying reservoirs of human pathogens in the environment and working to limit illness by encouraging growth of native, beneficial bacteria that will compete against pathogens for resources.
