[Effect of Actoflor preparations on survival of Escherichia coli M-17 and Salmonella enteritidis under starvation conditions in mixed cultures].
The viability of E. coli M-17 and S. enteritidis under starvation conditions in mono- and mixed cultures was studied. E. coli M-17 showed greater capacity for survival in mixed cultures than in monocultures, while for S. enteritidis the contrary was true. Preparations "Actoflor" enhanced the antagonistic activity of E. coli M-17, ensuring its absolute selective advantage under starvation conditions in mixed cultures. The role of E. coli M-17 low-molecular exometabolites is discussed; they are probably an important factor in the antagonistic activity of these microorganisms.
