Gluconic acid was produced in repeated batch processes with Aspergillus niger AM-11, immobilized in pumice stone particles using an unconventional oxygenation of culture media based on the addition of H2O2, decomposed by catalase to O2 and water. The highest gluconic acid productivity of 8.2 g l−1 h−1 was reached with 30 g immobilized mycelium per 150 ml, 10% (w/v) glucose, at 24 °C and pH 6.5, with O2 at 100% saturation. The immobilized mycelium was successfully reused up to 8 times in 1-h… CONTINUE READING
