各种细菌菌株在不良基质上生长期间表现出菌落分枝模式。这些模式反映了细菌的合作自组织和控制论过程中的通信，调节和控制殖民地的发展。一种建模方法是连续的或耦合的反应扩散方法，其中连续时间演化方程描述细菌密度和相关化学场的浓度。在分支生长的背景下，这个想法已经被许多团体所追求。我们提出了一个额外的模型，其中包括由细菌分泌的润滑液。我们还增加了领域的趋化剂的其他模型。然后，我们提出了一个批评，这整个企业的重点是模型的潜力，揭示新的生物特征。(C)1998 Elsevier Science B. V.保留所有权利。PACS：47.20.Hw; 87.10.e。
Various bacterial strains exhibit colonial branching patterns during growth on poor substrates. These patterns reflect bacterial cooperative self-organization and cybernetic processes of communication, regulation and control employed during colonial development. One method of modeling is the continuous, or coupled reaction-diffusion approach, in which continuous time evolution equations describe the bacterial density and the concentration of the relevant chemical fields. In the context of branching growth, this idea has been pursued by a number of groups. We present an additional model which includes a lubrication fluid excreted by the bacteria. We also add fields of chemotactic agents to the other models. We then present a critique of this whole enterprise with focus on the models' potential for revealing new biological features.
