In@lgae

Keywords: Simulation - Microalgae system - Productivity

Scientific Description The in@lgae simulation plateform is dedicated to the simulation of microalgae growth at different locations and for different periods of the year. The platform runs different submodels to account for the actual climate and compute biomass productivity together with the consumption of water, nitrogen, phosphorus, ... The platform runs models which describe mechanisms from fast time scale (dynamics of photosystems) down to slow time scales (growth photoacclimation). The models also include a description of the temperature evolution in the culturing systems. The simulation can also be coupled with a model of hydrodynamics as represented by the Freshkiss software developed by the Ange EPI.

Functional Description

In@lgae simulates the productivity of a microalgae production system, taking into account both the process type and its location and time of the year. The process is mainly defined by its thermal dynamics and by its associated hydrodynamics. For a given microalgal strain, a set of biological parameters describe the response to nitrogen limitation, temperature and light. As a result, the biomass production, CO${}_2$ and nitrognen fluxes, lipid and sugar accumulation are predicted.
