title: Diaminobutyricimonas aerilata gen. nov., sp. nov., a novel member of the family Microbacteriaceae isolated from an air sample in Korea.
abstract: A novel isolate, designated 6408J-67(T), was isolated from an air sample collected from Jeju Island, Republic of Korea. Its phenotypic, genotypic, and chemotaxonomic properties were compared with those of members of the family Microbacteriaceae. The Gram-positive, aerobic, motile rod formed light yellow, smooth, circular and convex colonies. Optimal growth occurred at 30°C and pH 7.0. 16S rRNA gene sequence data showed that the isolate was a novel member of the family Microbacteriaceae, with the highest sequence similarity (97.4%) to Labedella gwakjiensis KSW2-17(T) and less (<97%) sequence similarity with other taxa. The major cellular fatty acids (>10% of the total) were anteiso-C(15:0), iso-C(14:0), and iso-C(16:0). The strain also contained MK-13, MK-12, and MK-14 as the major menaquinones, as well as diphosphatidylglycerol, phosphatidylglycerol, and two unknown glycolipids. Its peptidoglycan structure was B1β with 2,4-diaminobutyric acid as a diamino acid. Mycolic acids were absent. The DNA G+C content was 68.3 mol%. Based on these phenotypic and genotypic findings, strain 6408J-67(T) represents a novel species of a new genus within the family Microbacteriaceae, for which the name Diaminobutyricimonas                 aerilata gen. nov., sp. nov. is proposed. The type strain is 6408J-67(T) (=KACC 15518(T) =NBRC 108726(T)).
