• Notes:
  • 🥇 Nomenclatural type of the genus Heliobacillus Beer-Romero and Gest 1998. Publication: Beer-Romero P, Gest H. Heliobacillus mobilis, a peritrichously flagellated anoxyphototroph containing bacteriochlorophyll g. FEMS Microbiol. Lett. 1987; 41:109-114.
  • ❗ Heliobacillus mobilis 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 Heliobacillus.
  • 😷 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 36 times in PubMed until 2025-06-04.
  • 🧍 According to Ludwig et al. (2021), this "species affiliates away from its type species and may be reclassified as Heliobacterium". Publication: Ludwig W, Viver T, Westram R, Francisco Gago J, Bustos-Caparros E, Knittel K, Amann R, Rossello-Mora R. Release LTP_12_2020, featuring a new ARB alignment and improved 16S rRNA tree for prokaryotic type strains. Syst Appl Microbiol 2021; 44:126218.
