Microorganisms are everywhere and mediate many important processes. These organisms are the unseen catalysts for industrial processes and are critical to many emerging technologies. This course will explore how microorganisms benefit society through bioremediation, food safety and production, and biotechnology. Lectures, outside readings, and in-class discussions will help students gain an understanding of where microbiology fits into broader discussions of sustainability, green technology, and human and environmental health. This course is designed for undergraduates in a variety of environmental and life science majors who desire to understand how microorganisms can improve the lives of humans and the environment around us.
