Dynamiques microbiennes et modélisation des cycles biochimiques terrestres

Abstract : The aim of this thesis is to study some problems related to the modeling of microbial ecosystems in soil. Consi- dering different physical and biogeochemical parameters, the reactif transport models are very performing to represent the biochemistry of a variably saturated porous media. In contrast, these models don’t integrate (or sparsely) the microbiological activities in the soils. The mathematical model of chemostat is frequently used in microbial ecology. For the purpose of a more simplified spatial representation than the reactif transport models, but sufficiently relevant to represent biological phenomena, this thesis is a first attempt to understand the "input- output" function in a structured chemostat, and to study how a special structure can alter this function, and what are the key parameters
