Abstract
We isolated 16 antibiotic-producing bacterial strains throughout the central Arctic Ocean, including seven Arthrobacter spp. with almost identical 16S rRNA gene sequences. These strains were numerically rare, as revealed using 454 pyrosequencing libraries. Arthrobacter spp. produced arthrobacilins A to C under different culture conditions, but other, unidentified compounds likely contributed to their antibiotic activity.
摘要
我们在整个北极中心洋中分离出 16 株产生抗生素的细菌菌株，其中包括 7 株几乎具有完全相同 16S rRNA 基因序列的节杆菌属。这些菌株的数量很少，这是通过 454 焦磷酸测序文库揭示的。节杆菌属在不同的培养条件下产生了arthrobacilins A 至 C，但其他未知化合物可能也对其抗生素活性有贡献。
