Abstract
A novel isolate designated 6408J67T 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 Grampositive aerobic motile rod formed light yellow smooth circular and convex colonies Optimal growth occurred at 30°C and pH 70 16S rRNA gene sequence data showed that the isolate was a novel member of the family Microbacteriaceae with the highest sequence similarity 974 to Labedella gwakjiensis KSW217T and less 97 sequence similarity with other taxa The major cellular fatty acids 10 of the total were anteisoC150 isoC140 and isoC160 The strain also contained MK13 MK12 and MK14 as the major menaquinones as well as diphosphatidylglycerol phosphatidylglycerol and two unknown glycolipids Its peptidoglycan structure was B1β with 24diaminobutyric acid as a diamino acid Mycolic acids were absent The DNA G+C content was 683 mol Based on these phenotypic and genotypic findings strain 6408J67T 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 6408J67T =KACC 15518T =NBRC 108726T
