Abstract
We detected polysaccharide capsules from Zunongwangia profunda SM-A87 with atomic force microscopy (AFM). The molecular organization of the capsules at the single-polysaccharide-chain level was reported. Furthermore, we found that with ScanAsyst mode the polysaccharide capsules could be detected even in the presence of deliquescent water covering the capsule.
摘要
我们利用原子力显微镜（AFM）检测到了深红红螺菌（Zunongwangia profunda）SM-A87 的多糖胶囊。我们报道了多糖胶囊在单多糖链水平上的分子组织。此外，我们发现，即使在覆盖胶囊的潮解水存在的情况下，使用 ScanAsyst 模式也可以检测到多糖胶囊。
