- Discuss microbial ecology and functional diversity of natural habitats.arrow_forwardWhile leafy greens are nutritionally rich, raw greens are also a significant source of foodborne illnesses. From 2014 to 2018, there were 51 foodborne disease outbreaks reported to the CDC linked to leafy greens, but the actual number of illnesses is likely much higher because more foodborne illnesses are not part of a recognized outbreak. Imagine you are a researcher interested in studying the microbial community on leafy greens from many different commercial sources. →You notice that many of the species identified are capable of forming biofilms. You hypothesize that biofilm formation is also important for causing foodborne illnesses. What features of biofilms would make them important in causing foodborne illness from leafy greens? What structural component(s) of the E. coli cell might play a role in initial biofilm formation on leafy greens?arrow_forwardDescribe nitrogen fixation, ammonification, nitrification, and denitrificationand how microbes are involved.arrow_forward

Give concrete and real examples.arrow_forwardDiscuss the different principles of microbial ecology.arrow_forwardDescribe the importance of the nitrogen and carbon cycles and the role of microbes in their maintenance. Discuss biofilms and their relevance to infectious diseases. Discuss population growth and the phases of a typical bacterial growth curve. Describe generation time for a bacterial population Explain how bacterial growth correlates to disease. Describe how environmental changes can alter the shape of a growth curve. Categorize microbes based on their preferred environmental niches (pH, temperature, oxygen and salt).
