The influence of gaseous metabolites of saprophytic soil bacteria on the growth and multiplication of L.monocytogenes and Y.pseudotuberculosis was studied. The study revealed that all cultures under study exhibited selectively both inhibiting and stimulating action on the multiplication of test cultures. Bacteria of the genera Pseudomonas and Acinetobacter showed the highest inhibiting activity with respect to the test cultures. Volatile metabolites of bacteria of the genus Aeromonas showed the highest stimulating activity. Methanol, according to the data of chromatographic analysis, supposedly played the main role in this process and was contained in the volatile substances of Aeromonas bacteria in greater amounts than in the volatile substances of Pseudomonas bacteria.
