这些含有细菌的微小沉积层被称为生物膜,它们存在于大多数表面和物体上。
These microscopic layers of deposits containing bacteria are known as biofilms and they are found on most surfaces and objects.
现在,美国加州大学洛杉矶分校(ucla)的研究人员及其同事已经发现,在生物膜形成的最初阶段,细菌实际上能够直立起来,并且能够“行走”,而直立“行走”是它们适应组织表面的一部分。
Now, UCLA researchers and their colleagues have found that during the initial stages of biofilm formation, bacteria can actually stand upright and "walk" as part of their adaptation to a surface.
表面活性素和其他类似的分子可造成细菌泄漏钾,此时生物膜开始形成。
Biofilm formation begins when surfactin, and other similar molecules, cause bacteria to leak potassium.
正在形成生物膜的细菌行为方式与自由态时是不同的,它会导致形成多层含有多聚糖的膜,覆盖在生物膜的表面成为保护层。
Bacteria in formatting biofilms behave differently than in a free state. This leads to the formation of layers containing polysaccharide which overlie the bacteria of the biofilm as a protector.
