title: [Description of some simple tests allowing the distinction between bacteriocins sensu stricto and other antibacterial agents produced by bacteria].
abstract: In contrast with other antibacterial agents produced by bacteria, the bacteriocins of Gram -- bacteria (briefly: cins G--) are characterized by their primary lethal action, their inactivation by trypsin, their resistance to pH 2 (in the crude state) and insensitivity to DNase I after treatment with 7 M urea. Only 4 among 26 studied cins G + have the 4 above-cited properties and share most properties of cines G--.
