Fungi have a well-established role in nutrient cycling and are widely used as agents in biological control and in the remediation of polluted landscapes. Competition for resources between different fungal communities is common in these contexts and its outcome impacts on the success of such biotechnological applications. In this investigation a mathematical model is constructed to represent competition between two fungal colonies that have access to different resources. It is shown that the model equations display a multitude of travelling wave solutions and that the outcome of competition between two fungal biomasses can be controlled through the simple manipulation of the nutrient resources available to each. The model equations are also numerically integrated to illustrate the range of outcomes arising from fungal competition and these results are placed in context of established experimental observations.
真菌在养分循环中发挥着既定作用，并且作为生物防治和污染景观修复的媒介被广泛应用。在这些情况下，不同真菌群落之间对资源的竞争很常见，其结果会影响此类生物技术应用的成功与否。在本研究中，构建了一个数学模型来描述两个可获取不同资源的真菌菌落之间的竞争。结果表明，该模型方程显示出多种行波解，并且通过简单地操控每个菌落可获取的营养资源，就能控制两种真菌生物量之间的竞争结果。还对方程进行了数值积分，以说明真菌竞争产生的各种结果范围，并将这些结果与已有的实验观察结果相结合。
