从博弈论的角度研究了两种都以糖为能源，但可以在两种不同的ATP产生途径之间进行选择的微生物。我们认为这些途径是不同的策略，我们分配的回报是成比例的预期稳定状态的个人可持续的基础上，这些策略。在一定的参数范围内，我们发现收益满足囚徒困境的条件。因此，合作行为不太可能发生，除非有其他因素干预。事实上，酿酒酵母使用竞争策略，即使在有氧条件下也会发酵糖，从而浪费了自己的资源。该模型的简单的量化结构应该能够访问一个实验确定的回报矩阵。
Two strains of microorganisms that both use sugar as energy resource, but which may choose between two different pathways of ATP production, are studied from a game-theory point of view. We consider these pathways as distinct strategies to which we assign payoffs that are proportional to the expected steady-state number of individuals sustainable on the basis of these strategies. In a certain parameter range, we find that the payoffs fulfil the conditions for the prisoner's dilemma. Therefore, cooperative behaviour is unlikely to occur, unless additional factors intervene. In fact, the yeast Saccharomyces cerevisiae uses a competitive strategy by fermenting sugars even under aerobic conditions, thus wasting its own resource. The simple quantifiable structure of the model should enable access to an experimentally determined payoff matrix.
