Optimization of Fermentation Medium for Extracellular Lipase Production from Aspergillus niger Using Response Surface Methodology

Figure 6

Response surface plot showing the effect of each factor on lipase activity obtained by A. niger G783. The medium was modified based on FM2. The values are average of three independent experiments and the error bars represent standard deviation.
