Complete genome of Polaribacter huanghezhanensis KCTC 32516 T isolated from glaciomarine fjord sediment of Svalbard.
Marine Genomics 2023 December
Polaribacter huanghezhanensis KCTC 32516T is an aerobic, non-flagellated, Gram-negative, orange-colony-forming bacterium that was isolated from the surficial glaciomarine sediment of inner basin of Kongsfjorden, Svalbard. The sampling site is characterized by a sedimentation of organic depleted lithogenous particles from the nearby glaciers, resulting in reduction of organic matter concentration. In order to understand microbial adaptation to the oligotrophic environment, we here sequenced the complete genome of the P. huanghezhanensis KCTC 32516T . The genome consists of 2,587,874 bp (G + C content of 31.5%) with a single chromosome, 2391 protein-coding genes, 39 tRNAs, and 2 rRNA operons. Our comparative analysis revealed that the P. huanghezhanensis possess the smallest genome in fifteen Polaribacter species with genome. The streamlined genome of this species, required less resource in replication, could evolved by the nutrient deficiency in surrounding environment. Simultaneously, the 15 KOs involved in amino acid biosynthesis and anaplerotic carbon fixation is uniquely absent in the P. huanghezhanensis. In addition, although the advantage of small genome, other 15 KOs involved in resource recycling and stress resistance is uniquely present in sequenced genome. This result demonstrates that the sequenced genome serves as a valuable model for further studies aimed at elucidating the molecular mechanisms associated with adaptation to oligotrophic habitat.
