Two-component bacterial predator-prey system immobilized on the surface ofa transparent plastic substrate is a promising model for investigation of the role of bacterial predators in ecosystems

Investigation of the adhesion and interaction of Bdellovibrio bacteriovorus and Pseudomonas fluorescens immobilized on the surface of a transparent pl astic substrate revealed the ability of bdellovibrios to live and reproduce in a biofilm on a solid surface. The dynamics of the population of free bd ellovibrios, bdelloplasts, and intact host cells studied by epifluorescence microscopy showed that two-component bacterial predator-prey systems immob ilized on the surface of a transparent plastic substrate are promising mode ls for the investigation of the role of bacterial predators in various ecos ystems.
