A1 Samadpour, Mansour A1 Shao, ZongzeYR 2015 T1 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 aerius Shivaji et al. 2006. Request for an Opinion JF International Journal of Systematic and Evolutionary Microbiology, VO 65 IS Pt_9 SP 3228 OP 3231 DO https://doi.org/10.1099/ijsem.0.000408 PB Microbiology Society, SN 1466-5034, AB 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 7304T and Bacillus stratosphericus MTCC 7305T do not conform to the descriptions of the type strains of the respective species. Strains MTCC 7303T and MTCC 7304T were indistinguishable from Bacillus altitudinis DSM 21631T, while strain MTCC 7305T 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)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.000408
