Environmental Sensing System(Quorum Sensing) is a cell-density-dependent gene regulation mechanism that enables microorganisms to communicate with each other through chemical signaling molecules called autoinducers, which they continuously secrete into the external environment. This system allows bacteria to detect their own population density in the environment and, upon reaching a specific threshold (quorum), simultaneously alter gene expression to exhibit collective behavior. This mechanism e

Biofilms are self-protective, structurally complex microbial communities formed by microorganisms (bacteria, fungi, and some protists) adhering to surfaces. These structures create a tight matrix composed of extracellular polymeric substances (EPS) secreted by the cells. EPS contains polysaccharides, proteins, DNA, and lipids, providing both structural integrity and protective functions to the biofilm. Biofilms are commonly found on surfaces in contact with water, on soil particles, or on living
