Microbial Growth Equations/Math Flashcards
1
Q
generation time
A
g = t/n
g = generation time
t = time
n = number of generations
2
Q
number of generations (n)
A
Nt = No2^n
n = (log Nt - log No)/log 2
3
Q
specific growth rate (k)
A
Nt = Noe^kt aka ln Nt = ln No + kt
k = (ln Nt / ln No)/t
4
Q
how is k related to g
A
k = (ln2)/g
5
Q
what is Nt
A
cell concentration (cells per ml) at a particular time
6
Q
what is No
A
initial cell concentration
7
Q
what is k
A
specific growth rate = number of generations per unit time
