  • 🧍 After these two years had passed without anyone claiming to possess an authentic type strain or proposing a neotype strain, the Judicial Commission [3] has decided in favour of the request by Tindall et al. 2000 [2]. The genus name Pelczaria and the species name Pelczaria aurantia are to be placed on the list of nomina rejicienda [3]. Publication: Judicial Commission. Judicial Opinion No. 78. Int J Syst Evol Microbiol 2005; 55:515.
  • 🧍 Tindall et al. 2000 [2] requested that the Judicial Commission consider (i) that the organism currently deposited as ATCC 49321 and DSM 12801 be recognized as a member of the species Kocuria rosea; (ii) that the organism deposited as ATCC 49321 and DSM 12801 does not represent a strain of the species Pelczaria aurantia; (iii) to place the names Pelczaria and Pelczaria aurantia on the list of rejected names if a suitable replacement strain, or a neotype, cannot be found within two years (Rule 18c).
