❗ Reference information Spheroplasts are bacterial cells that have partially lost their cell wall. They retain the outer membrane and part of the cell wall, thus differing from protoplasts, in which the cell wall is completely removed. They are formed under the action of antibiotics (e.g., penicillin) or lysozyme.
