Abstract

Pseudomonas species are known for their diverse metabolic abilities and broad ecological distribution. They are fundamental components of bacterial communities and perform essential ecological functions in the environment. A psychrotrophic Pseudomonas sp. IT1137 was isolated from intertidal sediment in the coastal region of the Fildes Peninsula, King George Island, Antarctica. The strain contained a circular chromosome of 5,346,697 bp with a G + C content of 61.66 mol% and one plasmid of 4481 bp with a G + C content of 64.61 mol%. A total of 4848 protein-coding genes, 65 tRNA genes and 15 rRNA genes were obtained. Genome sequence analysis revealed that strain IT1137 not only is a potentially novel species of the genus Pseudomonas but also harbors functional genes related to nitrogen, sulfur and phosphorus cycling. In addition, genes involved in alkane degradation, ectoine synthesis and cyclic lipopeptide (CLP) production were detected in the bacterial genome. The results indicate the potential of the strain Pseudomonas sp. IT1137 for biotechnological applications such as bioremediation and secondary metabolite production and are helpful for understanding bacterial adaptability and ecological function in cold coastal environments.

从南极潮间带沉积物中分离出的新型假单胞菌 IT1137 的完整基因组序列显示其在低温下降解烷烃的潜力

假单胞菌以其多样化的代谢能力和广泛的生态分布而闻名。它们是细菌群落的基本组成部分，在环境中发挥着重要的生态功能。从南极洲乔治王岛菲尔德斯半岛沿海地区的潮间带沉积物中分离出了一种精神营养性假单胞菌 IT1137。该菌株含有一条长达 5,346,697 bp 的环状染色体，其中 G + C 含量为 61.66 摩尔%；还含有一条长达 4481 bp 的质粒，其中 G + C 含量为 64.61 摩尔%。共获得 4848 个蛋白质编码基因、65 个 tRNA 基因和 15 个 rRNA 基因。基因组序列分析表明，菌株 IT1137 不仅可能是假单胞菌属的一个新物种，而且含有与氮、硫和磷循环相关的功能基因。此外，在细菌基因组中还检测到了参与烷烃降解、外氨酸合成和环脂肽（CLP）生产的基因。研究结果表明，IT1137 假单胞菌菌株具有生物修复和次生代谢物生产等生物技术应用潜力，并有助于了解细菌在寒冷沿海环境中的适应性和生态功能。

期刊介绍： The journal publishes papers on all functional and evolutionary aspects of genes, chromatin, chromosomes and (meta)genomes of marine (and freshwater) organisms. It deals with new genome-enabled insights into the broader framework of environmental science. Topics within the scope of this journal include: • Population genomics and ecology • Evolutionary and developmental genomics • Comparative genomics • Metagenomics • Environmental genomics • Systems biology More specific topics include: geographic and phylogenomic characterization of aquatic organisms, metabolic capacities and pathways of organisms and communities, biogeochemical cycles, genomics and integrative approaches applied to microbial ecology including (meta)transcriptomics and (meta)proteomics, tracking of infectious diseases, environmental stress, global climate change and ecosystem modelling.
