This method can be standardized with more efficiency.
Can tell whether the bacteria is aerobic or anaerobic, as
aerobic ones need oxygen and colonise at surface . But anaerobic
ones colonise at lower end. (Sensitivity).
2) pour plate
It can determine the bacterial concentration , without the need
of any previous culture.
Can give precise results .
3) streak plate:
Helpful in isolation of separate pure colony from a mixed
bacterial culture.
Easy to perform, is less complex.
4) slants
Provides larger surface area for growth of bacteria.
