3. (a) Comparing the culture-dependant (e.g., colony forming units count) and DNA-
based (e.g., PCR) bacterial number quantification methods, what are the primary
disadvantages of using culture-dependent methods to quantify bacterial numbers in an
environmental sample? Use no more than three sentences or bullet points to present
your answer succinctly.

(b) At a local wastewater treatment plant receiving municipal wastewater, the
secondary treatment units have been performing severely under the designed
benchmarks, resulting in poor effluent quality. You, a wastewater treatment engineer,
suspected that the wastewater treatment microbes in the units might be inhibited.
What factors do you want to check to find out potential causalities of the inhibition?
List the most common four factors that you want to start your investigation with.

1. Draw and describe the possible result that may be observed on an agar plate that utilized a 4-streak quadrant method for isolation WITHOUT the conduct of proper aseptic techniques Source of inoculum: Tap water Characteristic of colony: Yellow, circular colony with entire margin and convex elevation Answer: 2. Using your fingers, you are asked to aseptically touch the surface of a sterile agar plate. Illustrate the possible result from this step if your fingers are (a) unwashed – touched various things prior to placing on agar surface, and (b) washed with soap or disinfected with 70% alcohol. Describe the relative abundance of microbial growth observed on the plates. Unwashed Washed
Hi, I am working on qPCR quantification for specific bacteria. However, when the CT value achieve greater than 30, it always shown high CT value differences in my duplication no matter I repeat the same set of experiment for those samples with low quality. My question is, what makes this happening? The other question is, how many CT value differences is acceptable for duplication?
A phagehunter performs a spot titer using standard techniques (3 ul of each dilution spotted to lawn) of a lysate obtained from an optimum webbed plate experiment. The phagehunter counts 8 plaques on the 10-7 dilution spot. Which of the following scenarios is the best choice for the phagehunter to do next? a.) The phagehunter has not achieved a high enough titer lysate to move forward with characterization experiments, so they should go back to the pick-a-plaque experiment. b.) The phagehunter has not achieved a high enough titer lysate to move forward with characterization experiments, so they should adopt a phage from direct isolation. c.) The phagehunter has not achieved a high enough titer lysate to move forward with characterization experiments, so they should try to make more optimum webbed plates. d.) The phagehunter has achieved a high enough titer lysate to move forward with characterization experiments.
