Explain Pour plate & spread plate ?

Answer

One of the advantages of pour plate is we can identify
whetheer bacteria is an anaerobe, aerobe or a facultative
aerobe.

In a pour plate, bacteria will trap in the agar and the
anaerobe and facultative anaerobe will grow within the
media.

For a spread plate, agar will have to be pour on top of the
solidified agar to create an anaerobic environment.

The pour plate is also less work . But contamination will
be a problem with spread plate and pour plate could help
in this issue.

One of the disadvantage of the pour plate is it will be
difficult when colonies are required to be picked for
further screening and analyses.
