Identification of strains Bacillus aerophilus MTCC 7304T as Bacillus altitudinis and Bacillus stratosphericus MTCC 7305T as a Proteus sp. and the status of the species Bacillus aeriusShivaji et al. 2006. Request for an Opinion

Int J Syst Evol Microbiol. 2015 Sep;65(9):3228-3231. doi: 10.1099/ijsem.0.000408. Epub 2015 Jun 25.


On the basis of 16S rRNA, rpoB, gyrB and pycA gene sequence analyses, characterization of biochemical features and other phenotypic traits and pulsed-field gel electrophoresis (PFGE) fingerprinting, it was ascertained that strains Bacillus aerius MTCC 7303T, Bacillus aerophilus MTCC 7304(T) and Bacillus stratosphericus MTCC 7305(T) do not conform to the descriptions of the type strains of the respective species. Strains MTCC 7303(T) and MTCC 7304(T) were indistinguishable from Bacillus altitudinis DSM 21631(T), while strain MTCC 7305(T) should be classified as a representative of a Proteus sp. Our attempts to find other deposits of the type strains of these species were unsuccessful. Therefore, the results support the Request for an Opinion on the status of the species Bacillus aerophilus and Bacillus stratosphericus by Branquinho et al. [Branquinho, R., Klein, G., Kämpfer, P. & Peixe, L. V. (2015). Int J Syst Evol Microbiol 65, 1101]. It is also proposed that the Judicial Commission should place the name Bacillus aerius on the list of rejected names if a suitable replacement type strain cannot be found or a neotype is not proposed within two years following the publication of this Request (Rule 18c).
