海藻酸盐主要来源于褐藻，是支持北极和南极地区海洋微生物生长的重要碳源。然而，缺乏对两极地区可培养细菌海藻酸盐利用途径的系统研究和比较。本研究从北极和南极地区分离到88株菌株，其中60株可以在以海藻酸盐为唯一碳源的培养基中生长。这些利用藻酸盐的菌株属于变形菌门和拟杆菌门的 9 个属。对26个海藻酸盐利用菌株的基因组进行了测序，基因组分析表明它们均含有与海藻酸盐利用相关的基因簇。变形菌门的藻酸盐转运系统与拟杆菌门不同，并且不同变形菌属之间可能存在独特的转运系统。进一步研究了海藻酸盐利用基因的生物地理分布模式。发现藻酸盐利用基因根据细菌分类学而不是地理位置聚类，表明藻酸盐利用基因在两个极地并不是独立进化的。这项研究系统地阐明了北极和南极地区可培养细菌的藻酸盐利用途径，为极地细菌藻酸盐利用途径的分布和进化提供了线索。
Alginate, mainly derived from brown algae, is an important carbon source that can support the growth of marine microorganisms in the Arctic and Antarctic regions. However, there is a lack of systematic investigation and comparison of alginate utilization pathways in culturable bacteria from both polar regions. In this study, 88 strains were isolated from the Arctic and Antarctic regions, of which 60 strains could grow in the medium with alginate as the sole carbon source. These alginate-utilizing strains belong to 9 genera of the phyla Proteobacteria and Bacteroidetes. The genomes of 26 alginate-utilizing strains were sequenced and genomic analyses showed that they all contain the gene clusters related to alginate utilization. The alginate transport systems of Proteobacteria differ from those of Bacteroidetes and there may be unique transport systems among different genera of Proteobacteria. The biogeographic distribution pattern of alginate utilization genes was further investigated. The alginate utilization genes are found to cluster according to bacterial taxonomy rather than geographic location, indicating that the alginate utilization genes do not evolve independently in both polar regions. This study systematically illustrates the alginate utilization pathways in culturable bacteria from the Arctic and Antarctic regions, shedding light into the distribution and evolution of alginate utilization pathways in polar bacteria.
