BACTERIA GROWTH CURVE
Bacterial growth follows a regular pattern that
consists of four phases
Lag Phase – Bacteria inhibit little or no growth.
The bacteria adjust to their surroundings during
the lag phase.
Log Phase – Bacteria growth is very rapid during
the log phase with bacteria doubling the numbers
every few minutes
Stationary Phase – The numbers of bacteria being
produced equally the numbers of organisms that
are dying off during this phase. The bacteria have
to used up much of the space, nutrients and
moisture.
Decline Phase – Bacteria die off rapidly
because they lack nutrients and are poisoned
by their own toxic wastes
