Role of distant interactions in the regulation of the adhesion ofpseudomonas fluorescens cells

The effects of distant interactions (LRI) and culture air on the adhesion ofPseudomonas fluorescens cells were studied. OneP. fluorescens culture was found to diminish the adhesion of cells of another, glassscreened,P. fluorescens culture by 30% (in the absence o air exchange between cultures). This effect was interpreted to be due to penetrating LRI. Under the combined action ofLRI and culture air (the latter alone reduced cell adhesion by only several percent), the amount of unattached cells increased 2-to 30-fold (on the average, by a factor of nine). Such a great reduction of cell adhesion indicated the synergistic action ofLRI and culture air.
