Penicillins are antibiotics that interfere with proper cell wall formation in bacteria.
Penicillins would have no effect on Mycoplasma, because this genus of bacterium has no cell wall, and penicillin functions by interfering with cell wall formation, killing actively dividing bacteria that have cell walls. Penicillin is only effective against cells that are dividing, that is cells that must synthesize new cell wall components.
