• Notes:
  • According to Dunlap et al. (2016), this species is a later heterotypic synonym of Bacillus axarquiensis Ruiz-García et al. 2005 but this is in conflict with the rules of the International Code of Nomenclature of Prokaryotes. Publication: Dunlap CA, Bowman MJ, Schisler DA, Rooney AP. Genome analysis shows Bacillus axarquiensis is not a later heterotypic synonym of Bacillus mojavensis; reclassification of Bacillus malacitensis and Brevibacterium halotolerans as heterotypic synonyms of Bacillus axarquiensis. Int J Syst Evol Microbiol 2016; 66:2438-2443.
  • According to Tindall (2017), this species is an earlier heterotypic synonym of Bacillus axarquiensis Ruiz-García et al. 2005. Publication: Tindall BJ. The consequences of Bacillus axarquiensis Ruiz-Garcia et al. 2005, Bacillus malacitensis Ruiz-Garcia et al. 2005 and Brevibacterium halotolerans Delaporte and Sasson 1967 (Approved Lists 1980) being treated as heterotypic synonyms. Int J Syst Evol Microbiol 2017; 67:175-176.
  • According to Tindall (2017), this species is an earlier heterotypic synonym of Bacillus malacitensis Ruiz-García et al. 2005. Publication: Tindall BJ.

  • According to Tindall (2017), this species is not an earlier heterotypic synonym of Bacillus mojavensis Roberts et al. 1994. Publication: Tindall BJ. The consequences of Bacillus axarquiensis Ruiz-Garcia et al. 2005, Bacillus malacitensis Ruiz-Garcia et al. 2005 and Brevibacterium halotolerans Delaporte and Sasson 1967 (Approved Lists 1980) being treated as heterotypic synonyms. Int J Syst Evol Microbiol 2017; 67:175-176.
  • Brevibacterium halotolerans is the correct name 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 Brevibacterium.
