Surface plots for interactions between the different components of the media that were optimized to increase the DLA production by L. coryniformis subsp. torquens at 12h fermentation time where (a) represents the effect of yeast extract and meat extract, (b) sodium acetate and meat extract, (c) dipotassium phosphate and meat extract, and (d) dipotassium phosphate and sodium acetate. The effect of two variables with the other two variables maintained at their respective zero
