Regulation of the adhesion ofPseudomonas fluorescens cells to glass by extracellular volatile compounds

The effect of the gaseous metabolites of onePseudomonas fluorescens culture on the attachment of cells of anotherP. 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 charcoal and HAYESEP-Q adsorbent.
