Different relationships are formed inside the complex associations between microorganisms and plants in natural and artificial systems. The objective - the investigation of the utilization of volatile metabolites of germinating seeds by bacteria of the L. monocytogenes and Y. pseudotuberculosis species. The biological activity of volatile metabolites of germinating seeds of cabbage (Brassica oleacia), carrot (Daukus carota), salad (Zactuca sativa), and corn (Zea mays L.) against Listeria monocytogenes and Yersinia pseudotuberculosis was studied. It was shown that volatile metabolites are transfer factors and can be the sole carbon and energy source for these bacteria. These metabolites increased the reproduction of the studied bacteria by factors of 10–100 as compared to the control. An analysis of the data led to the conclusion that the Listeria and Yersinia reproduction intensity in the presence of the volatile metabolites of the plant mixture depended on the bacterial type. It is seen that volatile compounds of germinating seeds of corn, carrots, salad, and cabbage contain acetaldehyde, methanol, and ethanol in sufficiently high concentrations. The greatest amount of methanol was secreted by the corn seedlings. One of the main substances that affect the reproduction of Listeria was methanol. The data suggest that Yersinia, as well as Listeria, used methanol for nutrition under the conditions of a limited carbon source. Methanol is the main substance affecting their growth and reproduction.
