Notes:
1 According to Rules 27(3) and 30, this name is not validly published, because the original publication makes reference to the deposit of the type strain in a single recognized culture collection. However, according to the Judicial Opinion 81, Haloferax alexandrinus Asker and Ohta 2002 is considered to be validly published, since deposit in a second culture collection in a different country has been documented.

2 The genus name Haloferax is in the neuter gender. So, according to Rule 12c (1), Haloferax alexandrinus is an illegitimate name because the epithet must be in the neuter gender; i.e. alexandrinum, not alexandrinus.
