希瓦氏菌在各种环境中广泛分布。为了研究深海沉积物中耐压耐冷铁还原菌Shewanella piezotolerans WP 3的环境适应机制，测定了其基因组序列并进行了相关功能分析。WP 3的基因组由5，396，476个碱基对（bp）和4，944个开放阅读框（ORF）组成。它拥有许多基因或基因簇，帮助它科普极端的生活条件，如两套鞭毛系统的基因，结构RNA修饰，二十碳五烯酸（EPA）的生物合成和渗透物质的运输和合成。WP 3含有55个开放阅读框，编码推定型细胞色素，这与其广泛的环境适应能力有关。鉴定并比较了希瓦氏藻中参与不溶性金属还原的外基因簇。这两套鞭毛系统被发现在低温和高压下差异调节;侧鞭毛系统被发现是必不可少的，它的运动和生活在低温下。
Shewanellaspecies are widespread in various environments. Here, the genome sequence ofShewanella piezotoleransWP3, a piezotolerant and psychrotolerant iron reducing bacterium from deep-sea sediment was determined with related functional analysis to study its environmental adaptation mechanisms. The genome of WP3 consists of 5,396,476 base pairs (bp) with 4,944 open reading frames (ORFs). It possesses numerous genes or gene clusters which help it to cope with extreme living conditions such as genes for two sets of flagellum systems, structural RNA modification, eicosapentaenoic acid (EPA) biosynthesis and osmolyte transport and synthesis. And WP3 contains 55 open reading frames encoding putativec-type cytochromes which are substantial to its wide environmental adaptation ability. Themtr-omcgene cluster involved in the insoluble metal reduction in theShewanellagenus was identified and compared. The two sets of flagellum systems were found to be differentially regulated under low temperature and high pressure; the lateral flagellum system was found essential for its motility and living at low temperature.
