  Abstract:

  The batch fermentation kinetic of gluconic acid production has   been studied. The continuous
  fermentation process of glucose by Aspergillus niger to produce   gluconic acid under the influence of inlet substrate   concentration and hydraulic retention time has also been   investigated. The fermentation was modeled to be carried out in a   continuous stirred tank reactor. The results showed that at the   studied inlet glucose concentration of 150, 200, and 250 g/l, the   hydraulic retention time resulted in the increasing amount of   cell and gluconic acid concentration but decreasing glucose   concentration at the outlet stream of the reactor. The model   results also suggested that the possible range of hydraulic   retention time for the inlet substrate concentration of 150, 200,   and 250 g/l were 3-13, 8-12, and 7-11 h, respectively. Therefore   the recommended values of hydraulic retention time were 13, 12   and 11 h for the inlet substrate concentration of 150, 200, and   250 g/l, respectively.
