An aerobic bacterium, designated as strain KD337-16
T, was isolated from the fecal samples of a black pig. It exhibited spherical, non-motile and non–spore-forming, Gram-positive cells. KD337-16
T was identified as a member of the genus
Micrococcus through 16S rRNA gene sequencing, and its closest relatives were found to be
Micrococcus endophyticus YIM 56238
T (99.5% similarity),
Micrococcus luteus NCTC 2665
T (99.1%),
Micrococcus yunnanensis YIM 65004
T (99.1%),
Micrococcus aloeverae AE-6
T (99.1%),
Micrococcus antarcticus T2
T (98.9%), and
Micrococcus flavus LW4
T (98.7%). Phylogenomic trees were constructed, and strain KD337-16
T was found to form its own cluster as an independent lineage of
M. flavus LW4
T. Between KD337-16
T and its close relatives, the average nucleotide identity, average amino acid identity, and digital DNA–DNA hybridization were below the respective species delineation thresholds at 82.1–86.6%, 78.1–86.1%, and 24.4–34.9%. The major cellular fatty acids and polar lipids were anteiso-C
15:0 and iso-C
15:0, and DPG and PG, respectively. The predominant menaquinone was MK-8(H
2). Taken together, the results indicate that strain KD337-16
T is a novel species of the genus
Micrococcus, for which the name
Micrococcus porci sp. nov. is proposed. The type strain is KD337-16
T (=BCRC 81318
T = NBRC 115578
T).
