The factors’ effects on the anticipated responses (y) are displayed by the optimization curves including maximum LA productivity (g/L/h) with YE (A) and LA productivity without YE (B) at low and high levels. The optimum factor settings (Cur) were predicted with a composite desirability (d) of 1.00 (100%) with YE and 0.995 (99.5%) without YE.
