Sampling techniques Flashcards
1
Q
Why do perform sampling?
A
It allows us to take a measurement of the microorganisms within an area
2
Q
What type of bacteria do pour plates allow us to analyse?
A
Allows us to analyse anaerobic bacteria by covering them in a layer with agar
3
Q
What distribution describes the randomness of bacteria
A
The poisson distribution
4
Q
Why would we convert a graph scale to logarithmic?
A
It allows us to create predictors more accurately due to it smoothing out a curve
5
Q
Why are there lag phases within growth curves?
A
Sigma factors which stop all cellular function to force the cell to adapt to the new envionment
6
Q
Why does the stationary phase occur during the growth curve?
A
Cellular sensing causes the cells to communicate to stop growth due to lack of nutrients
