| Resumo: |
The aim of this work was to study the relation between citric acid production and respiration of Aspergillus niger LPB 21 in solid-state fermentation of cassava bagasse. The experiments were carried out in horizontal drum bioreactor coupled with a gas chromatography system. Fermentation was conduced for 144 h with initial substrate moisture of 60% using heat-treated cassava bagasse as sole carbon source. The exhausted air from the bioreactor was analyzed for the monitoring of CO2 produced and O2 consumed in order to estimate the biomass biosynthesis by the fungal culture. The metabolic activity of A. niger growth was associated to citric acid production. The system using FERSOL software determined 4.372 g of biomass/g of consumed O2. Estimated and analytically determined biomass values followed the same pattern showing that the applied mathematical model was adapted.
