Notes:
- ⏲ According to Satomi et al. (2002), this species is a later heterotypic synonym of Marinobacterium georgiense González et al. 1997 but this is in conflict with the rules of the International Code of Nomenclature of Prokaryotes. Publication: Satomi M, Kimura B, Hamada T, Harayama S, Fujii T. Phylogenetic study of the genus Oceanospirillum based on 16S rRNA and gyrB genes: emended description of the genus Oceanospirillum, description of Pseudospirillum gen. nov., Oceanobacter gen. nov. and Terasakiella gen. nov. and transfer of Oceanospirillum jannaschii and Pseudomonas stanieri to Marinobacterium as Marinobacterium jannaschii comb. nov. and Marinobacterium stanieri comb. no.

- ⏰ According to Tindall (2019), this species is an earlier heterotypic synonym of Marinobacterium georgiense González et al. 1997. Publication: Tindall BJ. Marinobacterium iners (Iizuka and Komagata 1964) comb. nov. arising from the Synonymy of Marinobacterium georgiense Gonzalez et al. 1997 and Pseudomonas iners Iizuka and Komagata 1964 (Approved Lists 1980).

- 🏢 Synonymy of this taxon was mentioned in an IJSEM list. Publication: Oren A, Garrity GM. List of changes in taxonomic opinion no. 31. Notification of changes in taxonomic opinion previously published outside the IJSEM. Int J Syst Evol Microbiol 2020; 70:9-10.
- 🏢 Synonymy of this taxon was mentioned in an IJSEM list. Publication: Oren A, Garrity GM. Validation list no. 191. List of new names and new combinations previously effectively, but not validly, published. Int J Syst Evol Microbiol 2020; 70:1-5.
- ❗ Pseudomonas iners is the correct name instead if this species is regarded as a separate species (i.e., if its nomenclatural type is not assigned to another species whose name is validly published, legitimate and not rejected and has priority) within a separate genus Pseudomonas.
- 😷 The risk group for Canada has been imported on 2024-02-27. The full classification is: risk group = 1, note = "Security sensitive biological agent: No - Terrestrial animal pathogen under Canadian Food Inspection Agency authority: No". — The risk group for Swiss Confederation has been imported on 2024-02-01. The full classification is: risk group = 1. — The risk group for Germany has been imported on 2023-10-29. The full classification is: risk group = 1. — If in doubt, use the risk group given in the regulations for your country and, if these are not available, use the risk group given in the catalogue of the culture collection from which you have obtained or intend to obtain the strain.
- 🎓 Name mentioned 3 times in PubMed until 2026-06-11.
- 🙅 This name is on the List of Recommended Names for bacteria of medical importance (LoRN) as a synonym of the name to be applied to this species. The name is on LoRN because of the recorded risk group of other species in the genus.
- 🧍 Pseudomonas iners and Marinobacterium georgiense are incorrectly unified as Marinobacterium georgiense González et al. 1997 emend. Satomi et al. 2002 [Rule 44].
