  abstract = {{E}nzyme production is a key concept of the metabolism of microbe populations. {E}xtracellular enzymes are notably responsible for the decomposition of the {P}articular {O}rganic {M}atter ({POM}) in order to feed the {D}issolved {A}vailable {M}atter ({DAM}) from where microbe populations and plants assimilate carbon ({C}), nitrogen ({N}) and phosphorus ({P}) based nutrients required for respiration and growth. {T}he resource allocation theory tend to show that the production of enzymes by microbes dynamically adapts to the current needs of the population and to the composition of the {POM} and the {DAM}. @ {H}owever, it would be unrealistic to simulate all possible enzymes species, and the exact chemical composition of areal world {POM} and {DAM} is assumed unknown. {I}n order to evaluate the decomposition of the substrate by a microbe population in this context, we propose the definition of generic enzymatic actions in a model called {B}uzy-pop. . {T}he notion of an enzymatic budget that can be allocated to each action allows to represent both constitutive and adaptive enzymatic activities according to the resource allocation theory. {A} multi-objective optimisation algorithm allocates the budget to available actions according to microscopic environmental conditions and life strategies of microbes, efficiently representing the decisions of microbe populations as the result of a compromise between sometimes contradictory objectives. {T}he {B}uzy-pop model finally allows to dynamically compute quantitative decomposition rates of labile and recalcitrant {C}, {N}and {P} over time in any {POM} and {DAM} composition, and is configurable thanks to a carefully chosen set of meaningful parameters that could be calibrated to fit results to real world cases. {B}ecause of its low input parameters requirements and its extensibility, {B}uzy-pop could be used in many contexts. {C}alibration is provided fora set of life strategies ({O}pportunists, {F}oragers and {M}inimalists) as an use case example. {E}xperimental results prove its consistency with theoretical expectations about the behaviour of microbe populations according to the proposed life strategies.},
