Bacterial growth, death and control of death

Why is a growth curve produced rather than a stepwise graph?

In the stationary phase, what happens to the number of viable cells?

What are some reasons for the stationary phase?

Like the exponential growth rate, the death rate is also usually...

Why might a small number of cells remain alive/the death rate slow towards after a significant period of death?

What is growth defined as?

Cell multiplication is a consequence of...

There is geometric progression in the generation time because...

What happens in binary fission?

What is a Z ring?

What is the calculation for the number of generations?

How does the growth of the peptidoglycan cell wall in a growing cell vary between bacilli and cocci?

What is the division time of E coli?

What is the calculation for the number of populations after a period of growth?

What is the division time in M. tuberculosis?

If chromosomal replication takes 40 minutes in E coli, how is its division time around half that?

In a closed system, why is population growth not exponential?

The rate of growth in a batch culture can be expressed in terms of the mean growth rate constant (k) i.e. the number of generations per unit time. What is the calculation for this?

Which two characteristics can be used to measure population growth?

What is the cell number?

What is the calculation for estimating population size by counting prokaryotes in a Petroff-Hausser chamber and counting eukaryotes in a haemocytometer?

What are two problems with haemocytometer counts for estimating the size of a population?

Using a spectrophotometer to estimate microbial population size by turbidity is inaccurate because...

Which 4 methods are common for performing a viable count?

Why must cultures be serially diluted before counting?

Why is a physiological saline solution preferred for dilutions?

When determining the total from a plate count, it is assume that 1 colony arose from...

Units of VIABLE counts are expressed as?

If you have the rate, how do you calculate the time for 1 generation to develop/double?

List some inaccuracies of performing counts.

What else can be measured to measure population growth, other than mass/turbidity/colonies?

What are the four stages of bacterial growth in batch culture?

List some environmental conditions that may affect microbial growth?

Why might the lag phase occur?

During the exponential/log phase, the microorganisms are dividing at the maximal possible rate, given which factors?
