Bactreria like Pseudomonas communicate with each other through a signallinmg cascade by formation of biofilm. this process is called quorum sensing. special molecules like AHl or Acyl homoserine lactones and Lux R tyupe of receptor molecules mediate this process. Since DMSO mimics the AHL molecule and thus help bacteria in formTION OF BIOFILM, SO THE BACTERIA IS ATTRACTED TOWARDS DMSO.
