is unique in that it can generate high current densities in bioelectrochemical systems (BES) operating under high salt conditions. This ability is important for the development of BES treating high salt wastewater and microbial desalination cells. Therefore, the genome of was characterized to identify proteins that might allow this strain to survive in high salt BES. Comparison to other species revealed that 81 of its 87 -type cytochromes had homologs in and . Genes coding for many extracellular electron transfer proteins were also detected, including the outer membrane -type cytochromes OmcS and OmcZ and the soluble -type cytochrome PgcA. also appears to have numerous membrane complexes involved in the translocation of protons and sodium ions and channels that provide protection against osmotic shock. In addition, it has more DNA repair genes than most species, suggesting that it might be able to more rapidly repair DNA damage caused in high salt and low pH anode environments. Although this genomic analysis provides invaluable insight into mechanisms used by to survive in high salt BES, genetic, transcriptomic, and proteomic studies will need to be done to validate their roles.
其独特之处在于，它能够在高盐条件下运行的生物电化学系统（BES）中产生高电流密度。这种能力对于处理高盐废水的BES和微生物脱盐电池的发展至关重要。因此，对[具体菌株名称未给出]的基因组进行了表征，以鉴定可能使该菌株在高盐BES中存活的蛋白质。与其他[相关物种名称未给出]物种的比较表明，其87种细胞色素中的81种在[相关物种名称未给出]和[相关物种名称未给出]中有同源物。还检测到许多编码细胞外电子转移蛋白的基因，包括外膜细胞色素OmcS和OmcZ以及可溶性细胞色素PgcA。[具体菌株名称未给出]似乎还具有许多参与质子和钠离子转运的膜复合物以及提供抗渗透冲击保护的通道。此外，它比大多数[相关物种名称未给出]物种拥有更多的DNA修复基因，这表明它可能能够更快速地修复在高盐和低pH阳极环境中造成的DNA损伤。尽管这种基因组分析为[具体菌株名称未给出]在高盐BES中存活所使用的机制提供了宝贵的见解，但仍需要进行遗传、转录组和蛋白质组研究来验证它们的作用。
