虽然许多遗传和生化因素对细菌运动性的影响已被广泛研究，但物理参数的影响研究有限。事实上，尽管自然环境通常是不对称的（例如拉伸的超分子结构），但大多数细菌行为实验都是在各向同性的液体溶液中进行的。在目前的工作中，我们表明，活微生物的行为是显着不同的媒体是不对称的。大肠杆菌的例子中游泳的散装单轴液体环境被用来证明这一现象。我们的研究结果提供了对细菌在真实的环境中遇到的条件下的行为的深入了解，并为控制它们的运动开辟了新的途径。
Although the influence on bacterial motility of many genetic and biochemical factors has been extensively studied, there have been limited studies of the impact of physical parameters. Indeed, despite the fact that natural environments are often asymmetric (such as stretched supramolecular structures), the majority of behavioral experiments with bacteria have been done in isotropic liquid solutions. In the present work, we show that the behavior of living microorganisms is dramatically different in media that are asymmetric. The example of Escherichia coli bacteria swimming in a bulk uniaxial liquid environment is used to demonstrate this phenomenon. The results of our study provide insight into the behavior of bacteria in conditions encountered in real environments and open new avenues for the control of their movements.
