Abstract

In present study, a Gram-stain-positive, non-motile, non-spore-forming, small spherical bacterium, strain S31T was isolated from skin surface (external ear lobe) of a healthy human subject and characterized using polyphasic approach of bacterial taxonomy. Based on 1507 bp 16S rRNA gene sequence comparison, strain S31T showed highest (92.8%, AY119686) sequence similarity with Macrococcus brunensis CCUG 47200T followed by Macrococcus caseolyticus DSM 20597T (92.7% AP009484) and formed a separate clade with 65% bootstrap support. The DNA G+C content was found to be 34 mol%. Anteiso C15:0, Anteiso C17:0 and iso C16:0 are the predominant fatty acids in fatty acid methyl ester (FAME) profile of strain S31T. It contained A3α type peptidoglycan with L-Lys- Gly3-L-Ala peptide. Comparative study of morphological and physiological traits indicated that strain S31T phenetically diverged from its closest relatives. Based on morphological, chemotaxonomic and genotypic data, strain S31T showed sufficient delineations from its closest relatives of family Staphylococcaceae and is proposed as a new genus Auricoccus with Auricoccus indicus as type species of the genus. Strain S31T (CCUG 69858T = KCTC 33611T = MCC 3027T) is the type strain of the species.
