The effect of soil bacteria ехоmetabolites on Listeria Monocytogenes reproduction

Author Affiliations


The influence of metabolites of saprophytic soil bacteria on the growth and reproduction of pathogens Listeria monocytogenes has been investigated. It has been shown that all investigated cultures have elective both inhibitive and stimulative effect on the test cultures reproduction. The Bacillus bacteria have revealed the highest catalytic activity to test cultures. The stimulation of L. monocytogenes growth in interaction with saprophyte strain exometabolites depended on the metabolite concentration, biological peculiarities of both saprophyte strain and listeria strain. The most optimal concentration of Bacillus pumilus with the revealed maximal stimulating effect has been selected.

Key words

Bacillus pumilus, Listeria monocytogenes, bacteria metabolites, saprophytic soil microorganisms, stimulation of growth
