Effect of C/N Ratio and Media Optimization through Response Surface Methodology on Simultaneous Productions of Intra- and Extracellular Inulinase and Invertase from Aspergillus niger ATCC 20611
Figure 2
Response surface showing the interaction between five parameters and extracellular invertase production (U/mL); (a) sucrose and NaNO3, (b) sucrose and Triton X-100, (c) yeast extract and Triton X-100, and (d) NaNO3 and Triton X-100. Other variables are constant at their center points. The numbers inside the contour plots indicate conversion yield (U/mL) of the extracellular invertase.
