康氏菌科海洋细菌的系统发育与代谢潜能研究进展

摘要康氏菌科(Kangillaceae)是海洋螺杆菌目(Oceanosprillales)下的科级分类单元,包含康氏菌属(Kangiella)、异康氏菌属(Aliikangiella)和Pleionea三个属。在康氏菌属高度精简的基因组中存在异常丰富的胞外蛋白酶编码基因,暗示此类海洋细菌对海洋颗粒有机物中的蛋白质成分降解具有重要贡献。鉴于已分离鉴定的康氏菌属模式菌株专一性利用蛋白类营养物质,我们建议将该属译为"食朊菌属"。本文将结合本实验室的研究进展,对康氏菌科细菌的分离培养过程、系统发育关系、代谢特点和潜在生态功能进行综述,为研究此类海洋细菌的生理生态功能提供思路。 Kangillaceae is a family under the order Oceanosprillales that contains the genera Kangiella,Aliikangiella and Pleionea.The presence of abundant genes encoding extracellular proteases in the highly streamlined genome of the genus Kangiella suggests that it contributes significantly to the degradation of protein components in marine particulate organic matter.Considering that the type strains of Kangilla exclusively utilize protein as nutrient sources,we suggest to translate the genus as"Shi Ruan Jun"(protein degrading bacteria)in Chinese.In this paper,we review the research progress to identify novel species and phylogeny of Kangielleace.based on the reconstituted metabolic networks of Kangiella,we reveal the potential ecological functions of this group of marine bacteria.
