• Notes:
  • ⏲ According to Dif et al. (2025), this species is a later heterotypic synonym of Geomonas diazotrophica Xu et al. 2022. Publication: Dif G, Djemouai N, Dif I, Meklat A, Zitouni A. Genome-based reclassification within Geomonas: Geomonas nitrogeniifigens Liu et al. 2022 as a heterotypic synonym of Geomonas diazotrophica Xu et al. 2022 and Geomonas fuzhouensis Yang et al. 2023 as a later heterotypic synonym of Geomonas subterranea Liu et al. 2022. Int J Syst Evol Microbiol 2025; 75:6841. 🇩🇿
  • 🏢 Synonymy of this taxon was mentioned in an IJSEM list. Publication: Oren A, Göker M. Notification list. Notification that new names and new combinations have appeared in volume 75, part 7 of the IJSEM. Int J Syst Evol Microbiol 2025; 75:6893.
  • ❗ Geomonas nitrogeniifigens 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 Geomonas.
  • 😷 The risk group for Germany has been imported on 2026-08-13. 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 2 times in PubMed until 2026-06-11.
