我们介绍了微生物对纤维素进行生物降解的各种模型。这些模型依赖于复杂的化学机制，涉及纤维素链的结构，并且可以依赖于微生物群体的表型特征。然后，我们在多性状群体的背景下使用相应的模型。这导致经典的逻辑类型的繁殖率限制了大种群的增长，但更令人惊讶的是，以类似于需要合作互动（或有性繁殖）的种群中所见的影响的方式限制了太小的种群的增长。因此，这项研究提供了一个引人注目的例子，说明即使在没有任何实际合作的情况下，一些类似合作的机制也可以在结构化的生物群体中发生。
We introduce various models for cellulose bio-degradation by micro-organisms. Those models rely on complex chemical mechanisms, involve the structure of the cellulose chains and are allowed to depend on the phenotypical traits of the population of micro-organisms. We then use the corresponding models in the context of multiple-trait populations. This leads to classical, logistic type, reproduction rates limiting the growth of large populations but also, and more surprisingly, limiting the growth of populations which are too small in a manner similar to the effects seen in populations requiring cooperative interactions (or sexual reproduction). This study thus offers a striking example of how some mechanisms resemblingcooperationcan occur in structured biological populations, even in the absence of any actual cooperation.
