Bacteria Culture
Batch Culture
Bacteria are grown until the Stationary Phase
All bacteria are then removed
The product has been made

Antibiotics
Continuous Flow
Bacteria are maintained at the Log/Stationary Phase
This is done by.....
Removing ageing bacteria
This process is used for.....

Adding new bacteria
Keeping conditions constant
Reproduction
Binary Fission
Process
Bacteria Reaches a Certain Size
Copies it's DNA
Elongates & Splits
2 Bacteria are now formed
Stages of Growth
Lag Phase
