outer membrane

The outer membrane is a protective layer found in certain bacteria, acting like a tough shield. It surrounds the main cell wall and helps protect the bacteria from harmful substances, such as antibiotics or toxins. Composed mainly of lipids and proteins, it also plays a role in identifying and interacting with the environment. This membrane makes these bacteria more resistant and adaptable, contributing to their survival in various conditions. Overall, the outer membrane is a crucial part of the bacteria’s structure, providing both defense and functional versatility.
