how do bacteria benefit from using multiple autoinducer signals for quorum sensing
Quorum sensing For the bacteria to use quorum sensing constitutively, they must possess three characteristics: to secrete a signaling molecule, an autoinducer, to detect the change in concentration of signaling molecules, and to regulate gene transcription as a response.[1] This process is highly dependent on the diffusion mechanism of the signaling molecules. QS SignalingÂ molecules are usually secreted at a low level by individual bacteria. At low cell density, the molecules may just diffuse away. At high cell density, the local concentration of signaling molecules may exceed its threshold level, and trigger changes in gene expressions.[3]
