title: Differentiation of Streptococcus faecalis Andrewes and Horder and Streptococcus faecium Orla-Jensen based on the amino acid composition of their murein.
abstract: 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.
