Information based from LPSN 2021 Alteribacter is a genus of Gram-positive or Gram-variable, rod-shaped bacteria in the family Bacillaceae within the order Bacillales.
[6] For example, many phylogenetically unrelated species possess the ability to form endospores under aerobic conditions, yet this criterion was deemed sufficient for inclusion into the genus Bacillus.
Species can be found in Hungarian soda lakes and the rhizosphere soil of Populus euphratica tree in the Taklamakan desert.
There is one non-validly published species, 'Bacillus lacisalsi", that was also found to branch reliably with other members of the Alteribacter clade as well as share the unique molecular markers.
It is important to continually monitor and update these classifications as new Bacillus species are identified and their genome sequence and culture strain information becomes available.
