[Regulation of the adhesion of Pseudomonas fluorescens cells to glass by culture-produced volatile compounds].

The effect of the gaseous metabolites of one Pseudomonas fluorescens culture on the attachment of cells of another Pseudomonas fluorescens culture to glass was studied. Gaseous metabolites increased the number of unattached cells by 10-30% and the mean residence time of cells attached to glass by 100%. These effects were presumably due to the yet unidentified compound, which we called volatile antiadhesin. This compound could be adsorbed by activated carbon and HAYESEP-Q adsorbent.
