Abstract Using laminar flow chambers and time-lapse video imaging, colonization of surfaces by four marine bacteria revealed a diverse range of morphological characteristics and cell-cell interactions. The strain SW5 formed a compact, multilayered single- and double-cell biofilm on hydrophobic surfaces but developed long multicellular chains on hydrophilic surfaces. The morphologically similar SW8 showed unusual proximal vertical packing of cells on both substrata.Vibrio sp strain S14 exhibited cyclical colonization-detachment events on both substrata.Pseudomonas sp strain S9 initially displayed reversible and then irreversible adhesion apparently triggered by a cell density phenomenon that led to the development of regular microcolonies on both substrata with individual cells translocating between the colonies. The length of time bacteria were exposed to and their density at a surface influenced behavioral traits, with diverse and distinctive species-specific behavioral events.
