Differentiation of Streptococcus faecalis Andrewes and Horder and Streptococcus faecium Orla-Jensen based on the amino acid composition of their murein.
The amino acid composition of the murein (peptidoglycan) of 75 strains of enterococci was investigated. All strains designated Streptococcus faecalis according to their physiological properties contained the lysine-alanine type of murein; all strains classified as S. faecium contained the lysine-aspartic acid type of murein.
