Abstrakt: The effect of the preparation of E. coli M-17 low-molecular exometabolites (Actoflor), containing growth autostimulators, on the growth of pure cultures of E. coli M-17 E. coli K-12, Salmonella enteritidis, Serratia marcescens and Bifidobacterium adolescentis MC-42 was studied. This preparation was shown to stimulate the growth of all above-mentioned bacteria. The addition of Actoflor also led to the acceleration of growth in the cultivation of mixed cultures of E. coli M-17 with E. coli K-12 (or S. enteritidis), the producer strain (E. coli M-17) showing the highest degree of acceleration. Moreover, the action of Actoflor led to the elimination of competitor strains and to the increase of the antagonistic activity of E. coli M-17. Actoflor may be supposedly used as a therapeutic or prophylactic remedy.
