RESUMEN
Salipiger manganoxidans VSW210T was compared with Salipiger marinus CK-I3-6T to examine the taxonomic relationship between the two type strains. In phylogenetic trees drawn using whole genome sequences and 16S rRNA gene sequences, S. manganoxidans VSW210T and S. marinus CK-I3-6T clade together and showed a 99.6â% 16S rRNA sequence similarity. The average amino acid identity (AAI), average nucleotide identity (ANIb and ANIm) and digital DNA-DNA hybridization (dDDH) values between S. manganoxidans VSW210T and S. marinus CK-I3-6T were below 97.5, 97.4, 98.4 and 85.1±2.5â%, respectively, all of which were greater than the species delineation threshold AAI value (95.5â%), ANI value (95-96â%) and dDDH value (70â%). Most phenotypic features between both species were almost identical, although there were some differences. The present results show that Salipiger manganoxidans is a later heterotypic synonym of Salipiger marinus.
