中文简介: | 我们提出了一种新的基于个体的移动细菌产生生物膜的模型。该模型基于这样一种假设,即细菌具有布朗运动,并产生一种聚合物物质,通过增加局部粘度来降低其流动性。我们将生物膜定义为聚合物及其所含细菌。我们的模拟结果表明,细菌的流动性增加了生物膜的异质性和复杂性(我们用熵测量来评估)。所获得的生物膜图案与生物膜显微照片的实验观察显示出良好的定性一致性。 |
课程简介: | We propose a new individual-based model of mobile bacteria producing a biofilm. The model is based on the assumption that bacteria have a brownian motion and produce a polymeric substance that reduce their mobility by increasing local viscosity. We define the biofilm as the polymeric substance together with the bacteria it contains. Our simulation results show that bacteria mobility increases the heterogeneity and the complexity of the biofilm (that we evaluate with an entropy measure). The obtained biofilm patterns show good qualitative agreement with experimental observation of biofilm micrographs. |
