title: The murein of citrobacter O-serogroup Ci23 Vi+.
abstract: The isolation and analysis of the Citrobacter O-serogroup Ci23Vi+ murein are described. The murein consists of alanine, glutamic acid, diaminopimelic acid (occurring in the molar ratio 1.5 : 1: 0.9), N-acetylmuramic acid and N-acetylglucosamine. Dialysable products resulting from the digestion of the Citrobacter O-serogroup Ci23Vi+ murein with egg white lysozyme resemble closely those obtained from the E. coli B murein.
