While 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?
An overgrowth of microbes can decrease dissolved oxygen levels to the point where organisms cannot survive.
True or False?
All of the following are ways microorganisms adapt to limited nutrients except:
synthesize increased amount of enzymes for uptake and metabolism of limited nutrients
form metabolically active highly resistant endospores
synthesize enzymes needed to use a different nutrient acetic acid
adjust the rate at which they metabolize nutrients
