• Notes:
  • As the type strain is not available from any established culture collection, nor from the authors who originally described the species, Kimura et al. 2016 propose to place the name on the list of rejected names if no replacement is found within two years (Request for an Opinion, Int J Syst Evol Microbiol 66, 3249 – 3251).
