Two morphological types of appendages, an anchor-like appendage and a peritrichate fibril-type appendage, have been observed on cells of an adhesive bacterium, Acinetobacter sp. strain Tol 5, by use of recently developed electron microscopic techniques. The anchor extends straight to the substratum without branching and tethers the cell body at its end at distances of several hundred nanometers, whereas the peritrichate fibril attaches to the substratum in multiple places, fixing the cell at much shorter distances.
利用最近开发的电子显微镜技术,在一种粘附性细菌——不动杆菌属Tol 5菌株的细胞上观察到了两种形态类型的附属物,一种是锚状附属物,另一种是周毛状纤维型附属物。锚状附属物笔直延伸至基质,无分支,并在其末端将细胞体固定在几百纳米的距离处,而周毛状纤维在多个位置附着于基质,将细胞固定在短得多的距离处。
