Note: CNCM is solely set up to deal with deposits on a confidential basis (i.e. patent deposits under the Budapest Treaty). Strain CNCM I-2120 is probably a patent deposit.

Notes:
1 The type strain of Pyrococcus horikoshii González et al. 1999 is not "JA-1 = JCM 9974" as stated in the Validation List no. 71, but simply JCM 9974.
Reference: Erratum. Int. J. Syst. Evol. Microbiol., 2000, 50, 1411.
2 The name Pyrococcus horikoshii must be attributed to González, Robb and Kato 1999 (in González, Masuchi, Robb, Ammermann, Maeder, Yanagibayashi, Tamaoka and Kato) not to González et al. 1999 as cited in Validation List no. 71.

Note: The name Pyrococcus woesei must be attributed to Zillig 1988 (in Zillig, Holz, Klenk, Trent, Wunderl, Janekovic, Imsel and Haas) not to Zillig et al. 1988 as cited in Validation List no. 24.

Pyrococcus yayanosii Birrien et al. 2011, sp. nov.
Type strain: (see also StrainInfo.net) strain CH1 = JCM 16557.
Sequence accession no. (16S rRNA gene) for the type strain: EU682399, CP002779 (complete genome).
Etymology: N.L. gen. masc. n. yayanosii, of Yayanos, in honour of Aristides Yayanos, a pioneer in the study of piezophilic bacteria.
Reference: BIRRIEN (J.L.), ZENG (X.), JEBBAR (M.), CAMBON-BONAVITA (M.A.), QUÉRELLOU (J.), OGER (P.), BIENVENU (N.), XIAO (X.) and PRIEUR (D.): Pyrococcus yayanosii sp. nov., an obligate piezophilic hyperthermophilic archaeon isolated from a deep-sea hydrothermal vent. Int. J. Syst. Evol. Microbiol., 2011, 61, 2827-2831.
Original article in IJSEM Online

Notes:
1 The type strain CH1 is deposited in only one culture collection with the accession number JCM 16557. However, Pyrococcus yayanosii Birrien et al. 2011 is validly published because a committee consisting of the Chairman of the ICSP, the Chairman of the JC of the ICSP and the Editor of the IJSEM has granted an exception in this instance to Rule 27(3) of the Bacteriological Code governing the deposit of type material in two different collections in two different countries. See minutes of the meetings of the International Committee on Systematics of Prokaryotes (ICSP) and its Judicial Commission (JC) in San Francisco in 2005.
