The strain was Gram-positive, halophilic, rod-shaped, aerobic and motile, could grow at 10-50 ℃, 0-20% (w/v) NaCl concentrations, pH 6.5-9.5, with optimal growth at 37 ℃, 5-10% (w/v) NaCl and pH 7.5. The lipidomic profile showed diphosphatidylglycerol, phosphatidylglycerol and one undetermined phospholipid as the major polar lipids. The whole cell analysis indicated MK-7 as the predominant menaquinone, meso-diaminopimelic acid with ribose and glucose-NH3 as the typical whole-cell sugars, anteiso-C15:0, iso-C16:0, iso-C15:0, iso-C14:0 as the main fatty acids. The genomic DNA G + C content was 40.4 mol%. A phylogenetic analysis based on the 16S rRNA gene of the strain YIM 98842T with publicly available reference data revealed that the YIM 98842T belongs to the genus Virgibacillus, with the highest similarity to Virgibacillus kimchii (98.25%) and Virgibacillus salarius SA-Vb1T (97.04%). The evidence of the phenotypic, chemotaxonomic, and phylogenetic analysis indicated that strain YIM 98842T represents a novel species of the genus Virgibacillus, for which the name Virgibacillus aidingensis sp. nov. is proposed. The type strain is YIM 98842T (= CGMCC 1.17259T = NBRC 114104T).PMID:41504983 | DOI:10.1007/s10482-025-02221-6
