Summary
A phenomenological model for the growth of Aspergillus niger on inert support in the packed bed is proposed and verified. The model deals with variables such as biomass, sugar, water, oxygen, carbon dioxide and bulk temperature. It is derived from mass and energy balance for each constituent and the kinetic term. To fit experimental results, saturation (Ks, 3.0 kg substrate m−3 packed), inhibition constant (Ki, 300 kg substrate m−3 packed) and maintenance coefficient of 3.0 E-06 kg substrate (kg wet biomass s)−1, were used.
Resume
Un modèle phénoménologique pour la croissance d’Aspergillus niger cultivé sur support inerte a été proposé et vérifié. Le modèle intègre 6 variables d’état : la biomasse, les sucres, l’eau, l’oxygène, le dioxyde de carbone et la température. Ce modèle a été construit à partir des bilans de masse et d’énergie de chaque constituant et des paramètres cinétiques. Pour ajuster le modèle aux résultats expérimentaux, nous avons, après une étude de sensibilité paramétrique, défini la constante de saturation du type Monod (Ks, 3,0 kg substrat m−3 compacté), une constante d’inhibition (Ki, 300 kg substrat m−3 compacté) et du coefficient de maintenance de 3.0 E-06 kg de substrat (kg de biomasse sèche s)-1.
