Bacillus gibsonii is a facultative anaerobe bacterium.{{cite journal|last1=Nielsen|first1=P.|last2=Fritze|first2=D.|last3=Priest|first3=F.

This species has been recently transferred into the genus Alkalihalobacillus.{{Cite journal|last1=Patel|first1=Sudip|last2=Gupta|first2=Radhey S.|date=2020-01-01|title=A phylogenomic and comparative genomic framework for resolving the polyphyly of the genus Bacillus: Proposal for six new genera of Bacillus species, Peribacillus gen. nov., Cytobacillus gen. nov., Mesobacillus gen. nov., Neobacillus gen. nov., Metabacillus gen. nov. and Alkalihalobacillus gen. nov.|journal=International Journal of Systematic and Evolutionary Microbiology|volume=70|issue=1|pages=406–438|doi=10.1099/ijsem.0.003775|pmid=31617837 |issn=1466-5026|doi-access=free}} The correct nomenclature is Alkalihalobacillus gibsonii.
