Boone and Kamagata 1998 requested a Judicial Opinion to reject the name Methanothrix soehngenii Huser et al. 1983 as a nomen confusum and to place this name on the list of rejected names. The Judicial Commission of the International Committee on Systematics of Prokaryotes has decided to place the genus Methanothrix with the species Methanothrix soehngenii Huser et al. 1983 on the list of nomina rejicienda, based on the fact that it is not represented by an axenic culture and contravenes Rule 31a of the International Code of Nomenclature of Prokaryotes. The species Methanothrix thermophila is transferred to the genus Methanosaeta as Methanosaeta thermophila (Kamagata et al. 1992) Boone and Kamagata 1998 comb. nov.

Int J Syst Evol Microbiol 2003; 53:933. In a request for an Opinion, Grant et al. proposed strain NCIMB 13488 as neotype of Halorubrum trapanicum, arguing that strain NRC 34021, derived from Petter’s original isolate of Halorubrum trapanicum is no longer available. They state, however, that the proposed neotype is also derived from Petter’s original isolate. The Judicial Commission decided that Halorubrum trapanicum strain NCIMB 13488 will not be the neotype, but since it is derived from NRC 34021, which in turn is derived from Petter’s original isolate, it is "a strain on which the original description was based" (Rule 18c), and may therefore also serve as the type strain of the species. Affected taxon names: Halorubrum trapanicum. Request for an opinion: Int J Syst Bacteriol 1998; 48:1077-1078. "Proposal of strain NCIMB 13488 as neotype of Halorubrum trapanicum.

Int J Syst Evol Microbiol 2003; 53:931. The Judicial Commission decided that Paenibacillus durus has priority over Paenibacillus azotofixans, further that the type strain of Paenibacillus durus is VPI 6563 (= ATCC 27763 = DSM 1735), not P3L5 (= ATCC 35681). Paenibacillus azotofixans is a later synonym of Paenibacillus durus. The argument that the specific epithet azotofixans would be more informative than the specific epithet durus cannot be taken into consideration when the priority is clear. Affected taxon names: Paenibacillus azotofixans. Request for an opinion: Int J Syst Bacteriol 1998; 48:325-326.

The Judicial Commission denied the Request for an Opinion by Dellaglio and Klein (1997), who had doubted the valid publication of Lactobacillus panis by Wiese et al.

The Judicial Commission decided that strain DSM 6035 is the type strain of Lactobacillus panis with the consequence, that the name Lactobacillus panis has been validly published. Affected taxon names: Lactobacillus panis. Request for an opinion: Int J Syst Bacteriol 1997; 47:910. "Rejection of Lactobacillus panis (Wiese et al. 1996). Request for an opinion."
Int J Syst Evol Microbiol 2003; 53:927. The Judicial Commission decided that the date of valid publication of the genus name Thermodesulfobacterium is 1995. This holds as well for the species name Thermodesulfobacterium commune with the type strain: YSRA-1 (ATCC 33708 = DSM 2178) and for the species name Thermodesulfobacterium thermophilum (originally described as Desulfovibrio thermophilus) with the type strain VKM V-1128. The type of the genus Thermodesulfobacterium is Thermodesulfobacterium commune.

Int J Syst Bacteriol 1999; 49:339. The name Clostridium putrificum is rejected while Clostridium botulinum is conserved for toxigenic strains and Clostridium sporogenes is conserved for non-toxigenic strains. Together with Opinion 60, this is one of the two examples for the rejection of names combined with the conservation of names in order to retain two distinct nomenspecies. As regulated by Rule 56a (5) Note 1, the treatment of names as perilous names is restricted to such situations.

Int J Syst Bacteriol 1993; 43:392. The name Citrobacter diversus Werkman and Gillen 1932 is placed on the list of nomina rejicienda because it was incorrectly used by Ewing and Davis in 1972 as the name for a new species that cannot be considered identical to the organism described by Werkman and Gillen and thus is a nomen dubium.

Int J Syst Bacteriol 1963; 13:33-35. "Rejection of Names of Bacteria in Certain Publications of Trécul, Hallier, Billroth, and Ogston" (cited from the title).(Only rejection of names, no conservation of counterparts. The phrasing would imply that the rejected names lose standing in nomenclature. In modern parlance, this would mean that they are not validly published. However, current revisions of the Code do not link the rejection of names with becoming not validly published.) Affected taxon names: Micrococcus. Request for an opinion: Int J Syst Bacteriol 1959; 9:185-194. "Request for an opinion relative to nomenclatural standing and acceptance of certain publications of Trécul, Hallier, Billroth and Ogston. Preliminary statement."
Int J Syst Bacteriol 1958; 8:171-172. "Rejection of the Generic Name Arthrobacter Fischer 1895 and Conservation of the Generic Name Arthrobacter Conn and Dimmick 1947" (cited from the title). The Opinion further indicates: "The name Arthrobacter proposed in 1895 as the name of a hypothetical genus of bacteria was not validly published and has no standing in nomenclature." Current revisions of the Code distinguish between rejected names and names that are not validly published. Affected taxon names: Arthrobacter. Request for an opinion: Int J Syst Bacteriol 1955; 5:83-84. "The status of the generic names Arthrobacter Fischer and Arthrobacter Conn and Dimmick. Preliminary statement."

In the case of Nitrosomonas Winogradsky 1892, conservation of a name and rejection ot its counterparts.

Int J Syst Bacteriol 1958; 8:166-168. "Status of the Generic Name Asterococcus and Conservation of the Generic Name Mycoplasma" (cited from the title). (Only conservation but no rejection of a name, and over all earlier homotypic synonyms.) It was also noted in this Opinion that the name over which Mycoplasma was conserved, Asterococcus Borrel et al. 1910, is illegitimate. Current revisions of the Code would imply that an illegitimate name may not be used anyway, hence conservation over an illegitimate name is unnecessary. Affected taxon names: Mycoplasma. Request for an opinion: Int J Syst Bacteriol 1955; 5:13-20. "The status and synonymy of the bacterial generic name Asterococcus. Preliminary statement."
