• Notes:
  • 🚂 For the type species of this genus another name is in use, which is affiliated with the genus Chryseobacterium Vandamme et al. 1994. Publication: Bajerski F, Ganzert L, Mangelsdorf K, Padur L, Lipski A, Wagner D. Chryseobacterium frigidisoli sp. nov., a psychrotolerant species of the family Flavobacteriaceae isolated from sandy permafrost from a glacier forefield. Int J Syst Evol Microbiol 2013; 63:2666-2671.
  • 🧔 This taxon was discussed in a meeting of a Taxonomic Subcommittee of the ICSP. Publication: Bowman JP, Hugo C, Nicholson A, Hahnke R, Lau EF, Holmes B, Sutcliffe I. International Committee on Systematics of Prokaryotes: Subcommittee on the taxonomy of aerobic Bacteroidota. Minutes of the online meeting 25 April 2023. Int J Syst Evol Microbiol 2023; 73:6144.
  • ❗ Halpernia is the correct name instead if this genus is regarded as a separate genus (i.e., if its nomenclatural type is not assigned to another genus whose name is validly published, legitimate and not rejected and has priority).
  • 🎰 The BRCs most frequently used for deposits in this group are: NBRC: 2; DSM: 2; KCCM: 1.
  • 🧍 While Nicholson et al. (2020) cited the publication of García-López et al. (2019), they did not address the critical comments made by García-López et al. (2019) regarding the dissection of Chryseobacterium. Publication: Garcia-Lopez M, Meier-Kolthoff JP, Tindall BJ, Gronow S, Woyke T, Kyrpides NC, Hahnke RL, Goker M. Analysis of 1,000 Type-Strain Genomes Improves Taxonomic Classification of Bacteroidetes. Front Microbiol 2019; 10:2083.
