The mDoE-toolbox was applied to maximize biomass growth for Desmodesmus pseudocommunis in a photobioreactor by varying the light intensity and pH and for Chlorella vulgaris in shake flasks, by varying the light intensity and duration. For both case studies, a mathematical mechanistic model was applied. In the first study only one experiment was necessary to adapt the mathematical model and identify a combination of light intensity and pH that improved biomass yield, as confirmed experimentally. In the second study, no well-established model was available for the specific experimental arrangement. On the basis of the literature, a mathematical model was constructed and a first cycle of mDoE was performed, thus identifying the desired factor combinations. Experiments confirmed the high biomass yield but revealed shortcomings of the model. The model was improved and a second cycle of mDoE was performed. The recommended factor combinations from both cycles were comparable. The mDoE was found to be a time-saving, cost-effective and useful method enabling the identification of factor combinations leading to high biomass production for the design of two different microalgae bioprocesses with low experimental effort.en2590-2628Current research in biotechnology2022102118Elsevierhttps://creativecommons.org/licenses/by/4.0/AlgaeChlorella vulgarisDesmodesmus pseudocommunisDoELight intensityMathematical process modelmDoEModel-assistedBiowissenschaften, BiologieTechnikModel-assisted DoE applied to microalgae processesJournal Article10.15480/882.422210.1016/j.crbiot.2022.01.00510.15480/882.4222Other
