[Role of distant cellular communications in regulation of Pseudomonas fluorescens adhesion]

The effects of long-range interactions (LRI) and culture air on the adhesion of Pseudomonas fluorescens cells were studied. One P. fluorescens culture was found to diminish the adhesion of cells of another, glass-screened, P. fluorescens culture by 30%. This effect was interpreted to be due to penetrating LRI. Under the combined action of LRI 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 of LRI and culture air.
