title: [Studies on the growth requirements of enterococci (author's transl)].
abstract: The growth requirements of biochemically defined strains of the enterococcus species Streptococcus faecium, S. faecalis, S. faecalis var. zymogenes and S. faecalis var. liquefaciens were compared. Arginine, glutamic acid, histidine, leucine, methionine and valine were essential and isoleucine, tryptophan, adenine and uracil were stimulatory to growth for all testes strains. Variation in the specific requirements occur for alanine, glycine, and serine representing strains differences. Threonine was essential for S. faecium strains but had no effect on the growth of strains of other species of enterococci.
