Chapter 6, Problem 2MCQ

Two culture media were inoculated with four different bacteria. After incubation, the following results were obtained:

Organism Medium 1 Medium 2
Escherichia coli Red colonies No growth
Staphylococcus aureus No growth Growth
Staphylococcus epidermidis No growth Growth
Salmonella enterica Colorless colonies No growth

2. Medium 2 is

  1. a. selective.
  2. b. differential.
  3. c. both selective and differential.

The thermal death point is best described as:(a) The highest temperature that will support growth of amicrobial culture(b) The length of time required for killing 100% of mi-crobes in a 24-hour culture that is heated to 100°C(c) The temperature at which a previously growing 24-hourculture will begin to die(d) The temperature at which 100% of the microbes in a24-hour culture will be killed in 10 minutes
).  Consider a culture medium on which only gram-positive organisms such as Staphylococcus aureus colonies can grow due to an elevated NaCl level. A yellow halo surrounds the growth, indicating the bacterium fermented sugar in the medium, decreasing the pH as a result and changing the color of a pH indicator chemical. This type of medium would be referred to as a(n): A) Selective medium. B) Differential medium. C) Enrichment culture. D) Selective and differential medium. E) Differential and enrichment culture.
You spread 0.1 mL volume of a 10^(-6) dilution onto a nutrient agar plate. After 24 hours of incubation at 37°C, there were 280 colonies of bacteria on the plate. A.) What is the original concentration (OCD) of bacteria in the stock sample this dilution came from?  B.) Using the OCD value from part A, determine the number of colonies that would be expected to grow on a plate that is inoculated with 0.1 mL volume of 10^(-8) dilution from this same stock of bacteria.  Show your work for both.
