• Homoserinimonas aerilata
• Microbacteriaceae
• 16S rRNA gene sequence
• DNA-DNA hybridization

A bacterial strain isolated from an air sample, strain 5317J-19(T), was characterized. The isolate was an aerobic, motile, Gram-positive rod. The organism was able to grow between 4 and 35A degrees C and between pH 6 and 9. The predominant fatty acids were anteiso-C-15:0 and iso-C-16:0. The major respiratory menaquinones were MK-12 and MK-11, and the minor ones were MK13, MK-10, and MK-9. Genomic DNA G+C content was 66 mol%. The diagnostic diamino acid of the peptidoglycan is presumably D-Orn. The peptidoglycan is supposed to be B2 beta type. The 16S rRNA gene sequence analysis indicated that this isolate belongs to the family Microbacteriaceae and had the highest sequence similarities with Salinibacterium xinjiangense 0543(T) (97.6%), Salinibacterium amurskyense KMM 3673(T) (97.2%), and Leifsonia bigeumensis MSL-27(T) (97.2%). Phylogenetic analysis and phenotypic characteristics support the proposal of a new genus and a novel species, with the name Homoserinimonas aerilata gen. nov., sp. nov. The type strain of Homoserinimonas aerilata is 5317J-19(T) (=KACC 15522(T) =NBRC 108729(T)).
