Bacteria break off and swim away with the help of flagella. Free-swimming bacteria attach to a living or nonliving surface. Signaling molecules enable bacteria to sense their numbers. e Slimy secretions protect attached bacteria and anchor them more firmly. Rectang Recruitment Swarm Mature biofilm Surface Slow growth of colony Dispersal from mature biofilm Attachment Quorum sensing Explosive growth
