To determine the specific growth rate of a bacterial population,it is essential to know

Accepted Answer

A)  cell concentrations at varied time points. 
B)  total number of cells in the population at varied time points. 
C)  cell concentrations at varied time points or the generation time.

Question 4

Sterility of a laminar flow hood is accomplished by filter-sterilized air passed through the hood quickly enough that non-sterile air does not flow into the work area.

Accepted Answer

A) True 
 B)False

Question 5

Which method would be LEAST effective at sterilizing a glass hockey stick to use in the spread-plate method?

Accepted Answer

A)  autoclaving 
B)  gamma radiation 
C)  ethanol soaking 
D)  ultrahigh-temperature pasteurization 
A)  autoclaving 
B)  gamma radiation 
C)  ethanol soaking 
D)  ultrahigh-temperature pasteurization

Question 6

Heterotrophic bacteria will run out of organic growth substrates in batch cultures but chemostats can provide constant nutrient source for them to grow.Chemostats for photoautotrophic bacteria are not necessary to maintain them at a constant growth phase because a light can artificially be turned on constantly.

Accepted Answer

A) True 
 B)False
