Name	Kind
"Bacillus putidus" Trevisan 1889	homotypic synonym, not validly published, basonym of name in Approved Lists
Arthrobacter siderocapsulatus Dubinina and Zhdanov 1975 (Approved Lists 1980)	heterotypic synonym, validly published under the ICNP

Notes:
- ⏰ According to Chun et al. (2001), this species is an earlier heterotypic synonym of Arthrobacter siderocapsulatus Dubinina and Zhdanov 1975 (Approved Lists 1980). Publication: Chun J, Rhee MS, Han JI, Bae KS. Arthrobacter siderocapsulatus Dubinina and Zhdanov 1975AL is a later subjective synonym of Pseudomonas putida (Trevisan 1889) Migula 1895AL.

- 🎓 Name mentioned 8053 times in PubMed until 2026-06-11.
- 🙆 This name is on the List of Recommended Names for bacteria of medical importance (LoRN) as the name to be applied to this species. The name is on LoRN because of the recorded risk group of the species itself.
- ⚠ This name is retained (and recommended for medical use. This will change in the future) instead of Pseudomonas parasichuanensis Tohya et al. 2026.

- 🧍 De Lorenzo et al. (2026) disagree with the decision to assign strain KT2440 to Pseudomonas alloputida rather than to Pseudomonas putida. Unfortunately, this is yet another paper that misrepresents prokaryotic nomenclature. The authors claim that the alleged problem arises because "the International Committee on Systematics of Prokaryotes (https://www.the-icsp.org) has issued an official, top-down change at the request of taxonomists who may have no working relationship with the organism" but they provide no evidence for this assertion. As the relevant sources indicate, this is not how the ICSP operates. There are no ICSP decisions on taxonomy, whether top-down or otherwise.
