论文摘要
我们将模型蓝细菌\ textit {Synechocystis}的聚类研究成小co菌。允许细菌扩散到不同硬度的表面上，并通过聚集和脱离与其他表面相互作用。我们发现，软表面会产生比硬菌丝更多。该作用与流动细胞比例给出的细菌动力学的异质性量有关。一个强调细胞之间特定相互作用的动力学模型，并通过考虑各种运动性的广泛数值模拟进行了补充，可以充分描述实验结果。高比例的动态细胞增强了色散而不是聚集。
We study the clustering of a model cyanobacterium \textit{Synechocystis} into microcolonies. The bacteria are allowed to diffuse onto surfaces of different hardness, and interact with the others by aggregation and detachment. We find that soft surfaces give rise to more microcolonies than hard ones. This effect is related to the amount of heterogeneity of bacteria's dynamics as given by the proportion of motile cells. A kinetic model that emphasizes specific interactions between cells, complemented by extensive numerical simulations considering various amounts of motility, describes the experimental results adequately. The high proportion of motile cells enhances dispersion rather than aggregation.
