Table 7

Input and response variables and optimization criteria for every response (output) (Case 2).

Input (independent) variables	Output (dependent) variables	Opt. criteria
𝑥1: tryptone (g L^−1)	𝑦1: biomass (g L^−1)	Minimize
𝑥2: yeast extract (g L^−1)	𝑦2: Oryza sativa nonsymbiotic hemoglobin1_OsHb1 (g L^−1)	Maximize
𝑥3: sodium chloride (g L^−1)
𝑥4: byproduct glycerol (g L^−1)
