In an attempt to provide a rational basis for the optimization of citric acid production by A. niger, we developed a mathematical model of the metabolism of this filamentous fungus when in conditions of citric acid accumulation. The present model is based in a previous one, but extended with the inc
Conidia of Aspergillus niger TMB 2022 were immobilized in calcium alginate for the production of citric acid. A 1-mL conidia suspension containing ca. 2.32 x IO'conidia were entrapped into sodium alginate solution in order to prepare 3% Ca-alginate (w/v) gel bead. Immobilized conidia were inoculated
Citric acid production in surface culture process with reuse of mycelia for more than one batch of media has been reported in this work. A strategy for replacing media and thus increasing productivity in subsequent batches is discussed. An explanation for the decrease in citric acid accumulation bey
