Question

A budding artisanal cheesemaker is trying to establish her own starter culture, but there
is an archaeal contaminant she finds difficult to get rid of. Instead of producing lactic acid,
the Archaea ferments the milk sugars into alcohol, an extremely undesirable effect in
cheese making, therefore ruining many of her cheesemaking efforts.
She asked microbiologists for help to find a strategy that may hinder the growth or even
kill the archaeal cells, but not the lactic acid bacteria (LAB) in rest of her starter culture.
The microbiologists come up with different things to try. In the table below are some
strategies that she tries.
Practice Question Chapter 3
5. Predict what the results are going to be for each strategy she uses. Assume each
inhibitor is specific. Assume she doesn't know the species of Archaea that is
contaminating her starter culture.
Answer yes, no, or maybe where appropriate, explain your answer in the last row
of the table below.

1) would you describe the contents of the soil-inoculated broth as being a “pure culture”? Why or why not? 2) How did the uninoculated broth differ in appearance from the broths inoculated with E. Coli and M. Luteus? And then how could you tell if a supposedly sterile, uninoculated broth was contaminated? Please explain in detail and highlight the important parts cuz I am confused and need help! Thanks
You are working for the CDC studying outbreaks of foodborne infectious disease. Your latest case is an incidence of food poisoning in a fast food restaurant. 5 people have been hospitalized for food poisoning, so you are working with that hospital to identify the source of the outbreak. Hospital clinicians have taken samples from each of the 5 patients for culturing. Each bacterial culture grew one likely microbe, each labelled P1, P2, P3, P4, and P5. All 5 isolates appear to have the same colony morphology on the plates, and all appear to be Gram-negative rods 1 micron wide and 3 microns long under the microscope. In addition, all 5 isolates appear to perform the same on an API 20E test strip that tests bacteria for 20 biochemical abilities. No other testing has been done yet. How would you best describe your set of isolates at this moment? O Each isolate is the same strain, of a different species O Each isolate is a different strain, of different species O Each isolate is a different…

About becterial enzymes, it is CORRECT to affirm that: a). Some becterial enzymes can help the microbe fight the immune system, by destroying lgA.b). Coagulases are enzymes that use the host's fibrinogen and form a semi-solid get that isolates amd protects the bacteria.c). Some bacterial enzymes such as hyaluronidase can help the microble move through the host's tissus by destroying the tissue's components.d). Fibrolysin is an enzymes that can help from blood clots.
A hospital lab technician working with a particular strain of streptococci culture on blood agar plates suddenly came down with a case of sore throat.
