CVE 5423 - Ecological Aspects of Environmental Microbiology

3 lecture hours 0 lab hours 3 credits
Course Description
This course examines processes mediated by bacteria in the natural and built environment. This includes areas such as nutrient transformations, decomposition of organic matter, pathogenesis, and use of microbes as vectors of genetic material. Adaptations that make these organisms fit for their functions will be identified, as well as how they interact with populations of other organisms and conditions in their native and non-native environments.  
Prereq: None
Note: This course is open to qualified undergraduate students.
Course Learning Outcomes
Upon successful completion of this course, the student will be able to:
  • Explain how environmental conditions affect nitrogen transformations such as nitritation, nitrification and anammox
  • Identify conditions that support the proliferation of environmental pathogens
  • Develop an understanding of how the inter-related activities of a consortium of microbes can function to create a pathway for degradation of organic matter
  • Use scientific literature to define the distribution and significance of specific bacteria of special importance to use of the natural environment by humans
