- You have several different media onto which you inoculated eight strains of yeast (A-H). The media include a rich medium, an unsupplemented minimal medium, and minimal media each supplemented with one vitamin. Of the yeast strains, one is a prototroph and seven are auxotrophs for a vitamin. After overnight incubation, the following results were observed (tan patches represent growth): D plate 1 (A) B DE F GH plate 5 plate 4 plate 6 Which plate contains an unsupplemented minimal medium? [Select] Which plate contains a rich medium? [Select] plate 2 Which strain is a prototroph? [Select] Strain E is an auxotroph for niacin. Which plate reveals this specific auxotrophy? [ Select] plate 3 plate 7 One strain is an auxotroph for both choline and pantothenic acid. Which one is this most likely to be? [Select]A phenylgalactoside-type compound, which yields galactose when enzymatically cleaved, was added as the sole carbon source to petri dishes containing E. coli culture medium. E. coli can utilize galactose for growth. Each of the following bacterial strains was plated on this medium and scored for growth after 1-2 days. Growth Genotype lacz+ lacI+ lacz+ lacIs lacz+ lacl- + oc lacZ+ lacI+ + a) What do you conclude about this compound with respect to its ability to be cleaved by ß- galactosidase? Why? b) What do you conclude about this compound with respect to its ability to inactivate the Lac repressor? Why? TIf a bacterial species is not susceptible to an antibacterial drug at the concentration present in a particular disk, does that necessarily mean the species is completely resistant to the drug? Explain your answer. What is the mode of action of bacitracin? How does this influence the types of bacteria it can be used against effectively? What is the mode of action of tetracycline? How does this influence the types of bacteria it can be used against effectively? Describe how populations of bacteria can evolve resistance to antibiotics. In your description, use the terms/phrases: mutation, resistant, sensitive, individuals, populations, natural selection, horizontal gene transfer.
- The table below shows the response of our ESKAPE safe relatives to 4 bacteria isolated from a master grid. We do not know the identity or any characteristics of the unknown bacteria. Each safe relative was spread onto a petri dish using aseptic technique. A grid pattern was taped to each plate and the unknown bacteria were patched into one of the squares. If there was no inhibition visible, including with a magnifying lens, the result was listed as -. If there was an inhibition zone between 1 and 10mm in diameter, the result is listed as +. If the inhibition zone was 10mm or greater, the result is listed as ++. In the lab, the MGC instructors plated all 6 of the ESKAPE pathogen safe relatives on LB agar plates. Then we patched Unknown Bacteria 5 from a Master plate onto the safe relative.

The presence of this bacterium in the nose and throat is widespread in the population, and in most people, colonization with Strep. pneumoniae is asymptomatic. The figure attached shows a comparison of in vitro growth curves of the wild-type strain of Strep. pneumoniae, as well as a Strep. pneumoniae mutant strain with a defect in one bacterial gene. The graph on the right shows the growth curve following addition of lysozyme during the logarithmic phase of bacterial growth. Which statement could account for the data in these graphs? Strain B is wild-type Strep. pneumoniae, and strain A is a mutant that cannot modify its peptidoglycan to be lysozyme-resistant. Strain B is wild-type Strep. pneumoniae, and strain A is a mutant that that expresses increased levels of LPS. Strain A is wild-type Strep. pneumoniae, and strain B is a mutant that cannot modify its…Order the following experimental steps to identify auxotrophic mutants in Saccharomyces Cerevisiae that cannot sythesize their own Leucine. an option can be selected more than once. step 1: Step 2: Step 3: Step 4: Step 5: Step 6:
