Quorum Sensing in Gram-Negative Bacteria: An Overview

Abstract

We know bacteria do not exist in solitary cell rather they try to live in colony. They try to communicate with each other by secreting some of chemical signals excreted from cell. The most common signaling molecule found in gram negative bacteria are N-acyl derivatives of homoserine lactone. In this article we try to give a general idea about how bacteria try to communicate with each other to monitor cell density before expressing a particular phenotypic character.
