摘要
The assembly of microbial communities through sequential invasions of microbial 物種 is challenging to study experimentally. Here, I used 基因組-scale metabolic models of multiple 物種 to model community assembly. Each such model represents all known biochemical reactions that a 物種 uses to build biomass from nutrients in the environment. 物種 interactions in such models emerge from first biochemical principles, either through competition for environmental nutrients, or through cross-feeding on metabolic by-products excreted by resident 物種. I used these models to study 250 community assembly sequences. In each such sequence, a community changes through successive 物種 invasions. During the 250 assembly sequences, communities become more 物種-rich and invasion-resistant. Resistance against both construct
