摘要

Flavobacterium arcticum SM1502(T), isolated from the surface seawater of Kings Fjord, Svalbard, Arctic, is an aerobic, non-flagellated, rod-shaped and yellow-pigmented bacterium belonging to the family Flavobacteriaceae. It is the first isolated Arctic Flavobacterium bacterium. To date, no genomes of Flavobacteriwn species isolated from the Arctic region have been sequenced. Here, we reported the complete genomic compositions and metabolic features of F. arcticum SM1502(T). The genome consists of 2,970,356 bp with an average GC content of 35.0%. A total of 2652 protein-coding sequences and 50 RNA genes were identified in the genome. SM1502(T) had lower protein pIs with higher ratios of acidic residues to basic residues compared to the relative bacteria and contains genes related to iron transport and organic osmoprotectant uptake, which could maintain cellular osmotic balance. These related genes and protein pI characteristics indicated that SM1502(T) has high salt tolerance and could accommodate the changing Arctic salty environments.
