Corrigendum to “Han's model parameters for microalgae grown under intermittent illumination: Determined using particle swarm optimization” [Journal of Theoretical Biology 437 (2018) 29–35]
Résumé
This work provides a model and the associated set of parameters allowing for microalgae population
growth computation under intermittent lightning. Han’s model is coupled with a simple microalgae
growth model to yield a relationship between illumination and population growth. The model parameters were obtained by fitting a dataset available in literature using Particle Swarm Optimization method.
In their work, authors grew microalgae in excess of nutrients under flashing conditions. Light/dark cycles
used for these experimentations are quite close to those found in photobioreactor, i.e. ranging from several seconds to one minute. In this work, in addition to producing the set of parameters, Particle Swarm
Optimization robustness was assessed. To do so, two different swarm initialization techniques were used,
i.e. uniform and random distribution throughout the search-space. Both yielded the same results. In addition, swarm distribution analysis reveals that the swarm converges to a unique minimum. Thus, the
produced set of parameters can be trustfully used to link light intensity to population growth rate. Furthermore, the set is capable to describe photodamages effects on population growth. Hence, accounting
for light overexposure effect on algal growth.
