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 a polyphasic approach. On the basis of 1507 bp 16S rRNA gene sequence comparison, 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 S31T has phenetically diverged from its closest relatives. On the basis of morphological, chemotaxonomic and genotypic data, S31T showed marked distinctions from its closest relatives of the family Staphylococcaceae and is proposed to represent a novel genus Auricoccus with Auricoccus indicus as type species of the genus. S31T (CCUG 69858T=KCTC 33611T=MCC 3027T) is the type strain of the species.

The genome-editing efficiency of the CRISPR-Cas9 system hinges on the recognition of the protospacer adjacent motif (PAM) sequence, which is essential for Cas9 binding to DNA. The commonly used (SpyCas9) targets the 5'-NGG-3' PAM sequence, which does not cover all the potential genomic-editing sites. To expand the toolbox for genome editing, SpyCas9 has been engineered to recognize flexible PAM sequences and Cas9 orthologs have been used to recognize novel PAM sequences.

Phylogenetic analyses based on 16S rRNA gene sequences of members of the family showed the presence of para- and polyphyletic genera. This finding prompted a thorough investigation into the taxonomy of the family by analysing their core genome phylogeny complemented with genome-based indices such as digital DNA-DNA hybridization, average nucleotide identity and average amino acid identity. The resulting data suggested the following proposals: was reduced in taxonomic rank as a later heterotypic synonym of ; subsp.
