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

Figure 3

The effect of nitrogen source on lipase activity obtained by A. niger G783. The medium was modified based on FM1. For the study on the effect of NaNO₃, 40 g/L soybean meal was supplemented in all runs. The values are average of three independent experiments and the error bars represent standard deviation.
