Bacterial Growth Curve Flashcards
1
Q
Lag phase
A
(1) The microorganisms are determine if the environment is conducive for growth Ex. Aw, Temp
2
Q
Log or exponential growth phase
A
(2) The environment is sufficient and organisms begin to grow due to sufficient oxygen availability, water activity, or temperature
3
Q
Stationary phase
A
(3) The number of cells growing is equal to the number of cells dying. Typically due to depleted nutrients such as the ones stated before
4
Q
Death or logarithmic decline
A
(4) The cells are no longer viable because the product was cooked, dried, or irradiated
5
Q
Y- axis
A
number of bacteria (log)
6
Q
X-axis
A
