摘要

研究人员从鳌山湾潮间带沉积物中分离到一株Gymnodinialimonas sp.57CJ19细菌，进一步检测表明该细菌具有降解抗菌防腐剂4-羟基苯甲酸酯的能力。对其完整的基因组序列进行了测序，系统进化分析表明，57CJ19菌株可能是Gymnodinialimonas属（罗杆菌科）的一个新物种。其基因组包含一个 3,861,607 bp 的环状染色体，G + C 含量为 61.25%。基因预测发现了 3716 个蛋白质编码基因、41 个 tRNA 基因、3 个 rrn 操作子和 3 个非编码 RNA 基因。功能注释揭示了 4-hydroxybenzoate 的完整代谢途径。57CJ19 菌株的基因组序列为了解海洋细菌降解芳香族化合物污染物的潜力和基因组基础提供了新的视角。

Complete genome sequence of the 4-hydroxybenzoate-degrading bacterium Gymnodinialimonas sp. 57CJ19, a potential novel species from intertidal sediments

A bacterium Gymnodinialimonas sp. 57CJ19, was isolated from the intertidal sediments of Aoshan Bay, and further assays showed that it has the ability to degrade the antibacterial preservative 4-hydroxybenzoate. The complete genome sequence was sequenced, and phylogenomic analyses indicated that strain 57CJ19 represents a potential novel species in the genus Gymnodinialimonas (family Rhodobacteraceae). Its genome contains a 3,861,607-bp circular chromosome with 61.25% G + C content. Gene prediction revealed 3716 protein-encoding genes, 41 tRNA genes, 3 rrn operons, and 3 non-coding RNA genes. Functional annotation revealed a complete metabolic pathway for 4-hydroxybenzoate. The genome sequence of strain 57CJ19 provides new insights into the potential and underlying genomic basis of aromatic compound pollutant degradation by marine bacteria.

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.
