[Evaluation of the bactericidal activity of chiral alkylammonium salts derived from N-benzoyl-amino acids with Escherichia coli and Bacillus cereus. I. -- Evaluation of the antibacterial activity (author's transl)].

Long-chained alkylammonium salts (C12 and C16) obtained from chiral N-benzoyl-amino acids were tested against Escherichia coli and Bacillus cereus, to evaluate their antibacterial efficacy. The bactericidal activity (MBC) determined by the membrane filtration technique and the bacteriostatic activity values suggested anionic group participation. The participation of the anion moiety, depended on nature and configuration of the amino acid. Stereoselective interactions appeared between bacteria and the cationic surfactants tested.
