• Emendations:
  • Spring et al. 1996 Spring S, Kämpfer P, Ludwig W, Schleifer KH. Polyphasic characterization of the genus Leptothrix: new descriptions of Leptothrix mobilis sp. nov. and Leptothrix discophora sp. nov. nom. rev. and emended description of Leptothrix cholodnii emend. Syst. Appl. Microbiol. 1996; 19:634-643.
    Notes:
    • 🧍 As of 2019-04-01 this emendation was not yet included in an IJSEM List of Changes in Taxonomic Opinion.
    • 🧍 The type strain LVMW 99 is lost, so Spring et al. 1997 propose to use the strain LMG 7171 as reference strain, until a neotype will be designated.
