Models of metabolism

Constraint-based metabolic modelling (CBMM)


Figure_3      Fluxes_distribution 


CBMM refers to the use of specific methods and tools to perform genome-scale metabolic simulations and infer cellular physiological features at the system-level. Microbiology is a promising application area for CBMM, due to the availability of many different data types and the necessity of an integrated, system-level understanding of the functioning of microbial communities.

We use CBMM for many purposes, from the understanding of microbial metabolism in extreme conditions to the elucidation of plant-microbes interactions, from the characterization of metabolic exchanges among different organisms, to the identification of potential drug targets.
