- ❗ Pseudomonas pseudoalcaligenes 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 authority of the taxon name (Stanier) deliberately differs from the authors of the publication (Stanier et al.).
- 😷 The risk group for Canada has been imported on 2024-02-27.
