“…B. lacisalsi was reported by Dong et al [7]. It was reported to be alkaliphilic, moderately halophilic and characterized by optimal growth at pH 9.0 and 8.0 % (w/v) NaCl [7]. B. lacisalsi is now a validly published species name [8] and hence in the present study, its taxonomic position was evaluated.…”

In the present study, the taxonomic position of Bacillus lacisalsi YSP-3T was evaluated using phylogenetic and genome-based comparison. B. lacisalsi YSP-3T showed the highest 16S rRNA gene sequence similarity to Alteribacter natronophilus M30T (98.4 %), followed by Alteribacter aurantiacus K1-5T (97.5 %) and Alteribacter populi FJAT-45347T (97.2 %). In phylogenetic (based on 16S rRNA gene sequences) and phylogenomic (based on 71 bacterial single-copy genes) trees, B. lacisalsi YSP-3T clustered with the members of the genus Alteribacter . The amino acid identity (AAI) values between B. lacisalsi YSP-3T and the members of the genus Alteribacter were >65 %, which is above the cut-off level (65–95 %) for genus delineation. The average nucleotide identity (ANI) values between B. lacisalsi YSP-3T and the members of the genus Alteribacter were <95 %, which is lower than the threshold value (95–96 %) for bacterial species delineation. The AAI value suggested that B. lacisalsi YSP-3T was a member of the genus Alteribacter while the ANIb value suggested it as a novel species of the genus Alteribacter . Based on the results, we propose to transfer Bacillus lacisalsi to the genus Alteribacter as Alteribacter lacisalsi comb. nov.

“…However, it was not transferred to the genus Alteribacter, as it was not a validly published species name. B. lacisalsi was reported by Dong et al [7]. It was reported to be alkaliphilic, moderately halophilic and characterized by optimal growth at pH 9.0 and 8.0 % (w/v) NaCl [7].…”

A Gram-stain-positive, aerobic, endospore-forming and rod-shaped bacterium (KQ-3T), which grew at 10–45 °C (optimum 35 °C), pH 8.0–10.5 (optimum pH 9.0) and in the presence of 0–16 % (w/v) NaCl (optimum 3.0 %), was isolated from a soda lake and identified as representing a novel species using a polyphasic taxonomic approach. Strain KQ-3T was catalase-positive, oxidase-negative and non-motile. Phylogenetic analysis based on 16S rRNA gene sequence affiliated KQ-3T to the genus Alteribacter and showed the highest similarities to Alteribacter natronophilus M30T (97.90 %), Alteribacter aurantiacus K1-5T (97.84 %) and Alteribacter populi FJAT-45347T (97.22 %). Digital DNA–DNA hybridization and average nucleotide identity analyses revealed that KQ-3T displayed 21.4 and 72.81% genomic DNA relatedness with the most closely related strain, A. natronophilus M30T, respectively. KQ-3T contained all of the conserved signature indels that are specific for members of the genus Alteribacter . The DNA G+C content was 45.03 mol%. The cell-wall peptidoglycan contained meso-diaminopimelic acid and the polar lipids consisted of phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol and one unidentified phospholipid. The predominant menaquinone was MK-7 (100%) and the major fatty acids (>10 %) comprised anteiso-C15 : 0, iso-C15 : 0 and iso-C16 : 0. Based on the data from the current polyphasic studies, KQ-3T represents a novel species of the genus Alteribacter , for which the name Alteribacter keqinensis sp. nov. is proposed. The type strain is KQ-3T (=ACCC 61799T=KCTC 33933T).
