Carotenoid-Producing Paracoccus aurantius sp. nov., Isolated from the West Coast of Dokdo Island, Republic of Korea.
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 MBLB3053T, 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 MBLB3053T 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 MBLB3053T. Using high-performance liquid chromatography, strain MBLB3053T 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 MBLB3053T represents a novel species within the genus Paracoccus, for which the name Paracoccus aurantius sp. nov is proposed. The type strain was MBL3053T (=KCTC 8269T =JCM 36634T). These findings support the research and resource value of this novel species, which was isolated from the Dokdo environmental microbiome.
期刊介绍:
The Journal of Microbiology and Biotechnology (JMB) is a monthly international journal devoted to the advancement and dissemination of scientific knowledge pertaining to microbiology, biotechnology, and related academic disciplines. It covers various scientific and technological aspects of Molecular and Cellular Microbiology, Environmental Microbiology and Biotechnology, Food Biotechnology, and Biotechnology and Bioengineering (subcategories are listed below). Launched in March 1991, the JMB is published by the Korean Society for Microbiology and Biotechnology (KMB) and distributed worldwide.
