  • 🧍 At the time of publication, the type strain was not deposited in two publicly accessible service collections in different countries, and Opitutus terrae Chin et al. 2001 was not validly published [Rules 27(3) and 30]. However, according to the Judicial Opinion 81, Opitutus terrae Chin et al. 2001 is now considered to be validly published, since deposit in a second culture collection in a different country has been documented.
