摘　　要：海神单胞菌属(Neptunomonas)于1999年被首次鉴定,目前包含8个菌种,其中6个已经完成全基因组测序。本文总结了海神单胞菌属的菌种特征和基因组信息,并利用基因组测序数据对该菌属的碳源利用途径、聚羟基脂肪酸酯代谢途径和芳香族化合物降解途径进行了分析。研究发现,海神单胞菌属具有完整的糖酵解和乙酸利用途径,普遍含有Ⅰ型和Ⅲ型的聚羟基脂肪酸酯合成酶,存在芳香族化合物的降解途径。基因组测序数据分析结果可以为海神单胞菌属在聚羟基脂肪酸酯合成与环境治理保护等领域的应用提供理论依据。Neptunomonas genus was identified for the first time in 1999. At present, a total of eight species have been discovered, and six of them have completed whole genome sequencing. This paper summarizes the phenotypic characteristics and genomic information of the Neptunomonas genus, and analyzes the carbon source utilization pathway, polyhydroxyalkanoate metabolism pathway and aromatic compound degradation pathway by using genomic sequencing data. It was found that the Neptunomonas genus has a complete glycolysis and acetic acid utilization pathway, generally contains type I and type Ⅲ polyhydroxyalkanoate synthase, and there is a degradation pathway for aromatic compounds. The results of genome sequencing data analysis can provide a theoretical basis for the application of Neptunomonas genus in the synthesis of polyhydroxyalkanoate and environmental protection.
