Questions And Answers With Verified
Solutions Already Passed Latest
Updated!!!
Given the following growth curve which letter correctly represents the different
phases - ANSWER✔✔ C: Stationary
B: Death
D: Exponential
A: Lag


Based on prior experiments, you have determined that for a culture of S. aureus
an absorbance reading of 1.0 AU650 is approximately equal to 4.5 x 10^6
cells/mL.
How many cells should be present after 6 generations in a 1 mL culture, if the
initial cell culture had an absorbance reading of 0.5? - ANSWER✔✔ 14000000


"AU" is an abbreviation for a species of bacteria, Aerogenes uflatulans -
ANSWER✔✔ False


In the graph shown immediately above, both of the growth curves pertain to
Vibrio natriegens. - ANSWER✔✔ True


"AU-25C" refers to the growth of a strain of E. coli called AU-25C, at temperature
of 37 degrees celsius - ANSWER✔✔ False


AU650 is directly related to the concentration of bacteria - ANSWER✔✔ True

,The generation time for Vibrio netriegens is longer at 45 degrees celsius than it is
at 37 degrees celsius - ANSWER✔✔ True


Vibrio natriegens grows faster than Escherichia coli - ANSWER✔✔ False


The optimal growth temperature for Vibrio natriegens is 37 degrees celsius -
ANSWER✔✔ False


Vibrio natriegens reaches stationary phase faster at 37 degrees celsius than at 25
degrees celsius - ANSWER✔✔ True


If the temperature gets above the optimal growth temperature, the bacteria will
be under stress and may die - ANSWER✔✔ True


A lower temperature makes an enzyme-catalyzed chemical reaction go faster
because the product is more stable - ANSWER✔✔ False


An increase in temperature, as long as it is at or below the optimal growth
temperature, helps bacteria to grow faster - ANSWER✔✔ True


For an enzyme-catalyzed chemical reaction, raising the temperature always
makes the reaction go faster - ANSWER✔✔ False


Given the above graph and data table, calculate the value of the growth rate
constant, k for E. coli in hr-1 - ANSWER✔✔ 2.3990

, Using the same data, calculate the value of the generation time, g for E. coli in
hrs. - ANSWER✔✔ 0.4168


Approximately how many generations occurred during exponential growth for E.
coli? - ANSWER✔✔ 3.9983


In which case would the shortest lag period most likely occur? - ANSWER✔✔
Transfer from old complex medium to fresh complex medium


How does incubating the culture with shaking influence growth of the bacteria? -
ANSWER✔✔ Shaking improves overall aeration, increasing oxygen content in the
media


The colorful bacteria that live in hot springs - ANSWER✔✔ Thermophile


Optimal growth at ~10 degrees celsius - ANSWER✔✔ Psychrophile


Optimal growth at ~65 degrees celsius - ANSWER✔✔ Thermophile


That weird smelling bacteria growing in your refrigerator - ANSWER✔✔
Psychrophile


Optimal growth at ~35 degrees celsius - ANSWER✔✔ Mesophile
