1. CE 3231 - Introduction to Environmental Engineering and Science Readings for Next Class : O hio N orthern U niversity Introduction Chemistry, Microbiology & Material Balance Water & Air Pollution Env Risk Management Microbiology From a mass and function point of view, our planet is the planet of the microbes. In fact, you have more microbial cells within your body than human cells. Without microbes, life on earth would not exist. For the next 5 classes, we will delve into the world of the unseen and piece together how microbiology relates to environmental engineering.

5. Microorganism Definition (wiki) – “an organism that is microscopic (usually too small to be seen by the naked human eye). The study of microorganisms is called microbiology, a subject that began with Anton van Leeuwenhoek's discovery of microorganisms in 1675, using a microscope of his own design”. http://en.wikipedia.org/wiki/Microorganism E. coli
