AB Toxic algae are a worldwide problem threatening aquaculture public health and tourism Alexandrium a toxic dinoflagellate proliferates in Northwest France estuaries (i e the Penze estuary) causing Paralytic Shellfish Poisoning events Vegetative growth and in particular the role of nutrient uptake and growth rate are crucial parameters to understand toxic blooms With the goal of modelling in situ Alexandrium blooms related to environmental parameters we first try to calibrate a zero-dimensional box model of Alexandrium growth This work focuses on phosphorus nutrition Our objective is to calibrate Alexandrium minutum as well as Heterocapsa triquetra (a non-toxic dinoflagellate) growth under different rates of phosphorus supply other factors being optimal and constant Laboratory experiments are used to calibrate two growth models and three uptake models for each species Models are then used to simulate monospecific batch and semi continuous experiments as well as competition between the two algae (mixed cultures) Results show that the Droop growth model together with linear uptake versus quota can represent most of our observations although a power law uptake function can more accurately simulate our phosphorus uptake data We note that such models have limitations in non steady-state situations and cell quotas can depend on a variety of factors so care must be taken in extrapolating these results beyond the specific conditions studied (C) 2010 Elsevier BV All rights reserved
