  • 🧍 In Kilian's opinion [1] the change of the well-established name Nitrosococcus oceanus may be a source of confusion. So, with reference to the first Principle of the Bacteriological Code (1990 Revision), Kilian requested that the original name Nitrosococcus oceanus be conserved [2]. The Judicial Commission denied this request, and no Opinion will be issued upon this request [3]. Publication: Kilian M. Necessary changes of bacterial names? ASM News 1998; 64:670.
