Glycine dependent Staphylococcus aureus var. bovis strains (TSCHÄPE and RISCHE 1971) were tested for their ability to grow on glycine containing and glycine deprived media. We observed glycine dependence only in minimal media. In complete media the strains grew in absence of glycine Testing the ability of some glycine precursors we found that in minimal media glycine could be replaced by threonine and in some cases by serine. One mutant (Gly 100 Glyox.r.) was able to metabolize glyoxylate instead of glycine Aspartic acid was metabolized in presence of glycine. Using 14 C‐aspartic acid we detected 14 C‐glycine and 14 C‐threonine. Presumably the bacteria metabolize aspartic acid to glycine via threonine.
