Fig. 5From: Enhancement of pullulanase production from recombinant Bacillus subtilis by optimization of feeding strategy and fermentation conditionsResidual sugar including glucose (blue curve) and sucrose (black curve) during fed-batch fermentation by feeding 500 g L−1 glucose solution. The averages of three independent experiments together with the corresponding standard deviations are shown for all values of OD600 and enzymeBack to article page
