Two factors affecting the adhesion of Pseudomonas fluorescens to glass surfaces were revealed in the culture liquid (CL) of this bacterium. One of these factors, adhesin, which is responsible for cell adhesion, was found to be a protein substance located both at the cell surface and in the CL, Bacterial cells grown in rich LB medium were less adhesive than cells grown in minimal M9 medium 1. The adhesive capacity of cells was independent of the growth phase. The other factor, antiadhesin (AA), which reduces cell adhesion, was found only in the CL. AA concentration in the CL increased with the culture age.
