The lowest viscosity that immobilized flagellated bacteria such as Psedomonas aeruginosa, Spirillum serpens, and Escherichia coli was 60 centipoise (cp). Much higher viscosities (1,000 cp and higher) were required to immobilize two flagellated bacteria selectively isolated from nature by methods based on their ability to migrate through agar gels. The latter finding indicates that certain flagellated bacteria have the ability to swim through environments of relatively high viscosity. It is suggested that these flagellated bacteria possess a specialized type of motility apparatus suited to viscous conditions present in their habitats.
使诸如铜绿假单胞菌、蜿蜒螺菌和大肠杆菌等具鞭毛细菌固定所需的最低粘度为60厘泊(cp)。而要固定通过基于其在琼脂凝胶中迁移能力从自然界中选择性分离出的两种具鞭毛细菌,则需要更高的粘度(1000 cp及更高)。后一发现表明,某些具鞭毛细菌有能力在粘度相对较高的环境中游动。有人提出,这些具鞭毛细菌拥有一种适合其栖息地粘性条件的特殊运动装置。
