Fig. 7From: Overexpression of membrane-bound gluconate-2-dehydrogenase to enhance the production of 2-keto-d-gluconic acid by Gluconobacter oxydans Comparison of 2KGA production from glucose. The biotransformations were carried out in 7-L fermenter at 30 °C, pH 5.8, 600 rpm, aeration rate 8 L/min, initial Glu concentration 200 g/L and cell concentration 60 g(wet wt)/L. a G. oxydans_tufB_ga2dh b G. oxydans_ pBBR1MCS5Back to article page
