  • Title: Effect of respiratory inhibitors on the motility of Pseudomonas fluorescens.
    Author: Faust MA, Doetsch RN.
    Journal: J Bacteriol; 1969 Feb; 97(2):806-11. PubMed ID: 4180008.
    Abstract:
    The translational motility of Pseudomonas fluorescens was weakly inhibited by oligomycin, Dicumarol, 2,4-dinitrophenol, 2n-heptyl-4-hydroxyquinoline N-oxide, and potassium cyanide. Atabrine and antimycin A together with potassium cyanide immediately immobilized this bacterium, but antimycin A alone was without effect. Gramicidin D also immobilized P. fluorescens, but its action was inhibited by K(+) and NH(4) (+) ions. In like manner, the effect of p-chloromercuribenzoate could be counteracted with cysteine, thereby suggesting the involvement of -SH groups in flagellar motility processes. It appears that the energy required for motility of P. fluorescens is generated by oxidative phosphorylation mediated by the cytochrome system.
