Abstract
- In this study, a novel species within the genus Paracoccus was isolated from the coastal soil of Dokdo (Seodo) Island and investigated. We elucidated the novel species, designated MBLB3053 <superscript>T</superscript> , through genomic analysis of novel functional microbial resources. Cells were gram-negative, non-motile, and coccoid, and the colony was light orange in color. Phylogenetic analysis based on the 16S rRNA gene showed that strain MBLB3053 <superscript>T</superscript> was related to the genus Paracoccus , with 98.5% similarity to Paracoccus aestuariivivens . Comparative genome analysis also revealed the strain to be a novel species of the genus Paracoccus by average nucleotide identity and in silico DNA-DNA hybridization values. Through secondary metabolite analysis, terpene biosynthetic gene clusters associated with carotenoid biosynthesis were found in strain MBLB3053 <superscript>T</superscript> . Using high-performance liquid chromatography, strain MBLB3053 <superscript>T</superscript> was confirmed to produce carotenoids, including all- trans -astaxanthin, by comparison to the standard compound. Notably, the isolate was also confirmed to produce carotenoids that other closely related species did not produce. Based on this comprehensive polyphasic taxonomy, strain MBLB3053 <superscript>T</superscript> represents a novel species within the genus Paracoccus , for which the name Paracoccus aurantius sp. nov is proposed. The type strain was MBL3053 <superscript>T</superscript> (=KCTC 8269 <superscript>T</superscript> =JCM 36634 <superscript>T</superscript> ). These findings support the research and resource value of this novel species, which was isolated from the Dokdo environmental microbiome.
