Grampositive bacteria.

True or False?

Answer: True. Selective media can be used to separate gram negative from gram positive bacteria.

Explanation: Selective media allow certain types of organisms to grow, and inhibit the growth of other organisms.

For example: Media containing potassium tellurite will inhibit the growth of gram negative bacteria while media supplemented with penicillin will inhibit the growth of gram positive bacteria.
