Abstract

Alginate is a natural marine polysaccharide and an important marine organic carbon source, which is mainly produced by marine brown algae. Marinobacter sp. M5B, a Gram-negative and aerobic bacterium, was isolated from the surface seawater samples collected from the Mariana Trench. Here, we report the complete genome sequence of strain M5B and its genomic characteristics to synthesize alginate. The genome of strain M5B contains one circular chromosome (4,415,647 bp) with the GC content of 57.14 %. Genomic analysis showed that strain M5B contained a set of genes involved in alginate synthesis, indicating that it possesses the potential ability to synthesis alginate. This study provides novel insights into alginate synthesis by marine microorganisms.

海洋杆菌M5B的基因组分析揭示了其在海藻酸盐生物合成中的作用

藻酸盐是一种天然的海洋多糖，是重要的海洋有机碳源，主要由海洋褐藻产生。从马里亚纳海沟表层海水样本中分离出革兰氏阴性需氧细菌M5B。本文报道了菌株M5B的全基因组序列及其合成海藻酸盐的基因组特征。菌株M5B基因组包含1条圆形染色体（4,415,647 bp）， GC含量为57.14%。基因组分析表明，菌株M5B含有一组参与海藻酸盐合成的基因，表明其具有潜在的合成海藻酸盐的能力。该研究为海洋微生物合成海藻酸盐提供了新的见解。

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.
