Marinobacter sp. strain LQ44, an alkaliphile and moderate halophile from a deep-sea hydrothermal vent on the East Pacific Rise, is a novel phenol-degrading bacterium that is capable of utilizing phenol as sole carbon and energy sources. Here, we present the complete genome sequence of strain LQ44, which consists of 4,435,564 bp with a circular chromosome, 4164 protein-coding genes, 3 rRNA operons and 50 tRNAs. Genome analysis revealed that strain LQ44 may degrade phenol via meta-cleavage pathway. The LQ44 genome contains multiple genes involved in pH adaptation and osmotic adjustment. Genes related to hydrocarbon degradation, aerobic denitrification and potential industrial important enzymes were also identified from the genome. To our knowledge, this is the first report of a genome sequence of a haloalkaliphilic phenol-degrading bacterium, which will provide insights into the survival of this bacterium under salt-alkali conditions and the potential for biotechnological applications.

马林杆菌sp。LQ44菌株是一种来自东太平洋上升沿深海热液喷口的嗜碱和中等嗜盐菌，是一种新型的苯酚降解细菌，能够利用苯酚作为唯一的碳和能源。在这里，我们介绍了菌株LQ44的完整基因组序列，该序列由具有环状染色体的4,435,564 bp，4164个蛋白质编码基因，3个rRNA操纵子和50个tRNA组成。基因组分析表明，菌株LQ44可能通过元裂解途径降解苯酚。LQ44基因组包含多个与pH适应和渗透调节有关的基因。还从基因组中鉴定了与烃降解，好氧反硝化和潜在的工业重要酶有关的基因。据我们所知，这是卤代嗜碱酚降解细菌基因组序列的首次报道，
