[Cell growth inhibitory compound from the culture of intestinal lactic acid bacteria].
The influence of the culture supernatants of 1000 strains of intestinal lactic acid bacteria on the growth of HeLa cells was examined. The compound from Enterococcus faecium 3463 showing the strongest cell growth inhibiting effect in these strains was isolated and identified as tyramine. The effect of tyramine was activated by the newborn bovine sera (NBS), but weakly by the fetal bovine sera (FBS). Benzylamine and beta-phenethylamine also showed the NBS-dependent cell growth inhibitory effect against HeLa cells.
