Figure 2
Response surface plots: (a) reaction time (h) versus agitation speed (r.p.m.); (b) enzyme amount (% w/w) versus reaction temperature (°C); (c) enzyme amount (% w/w) versus agitation speed (r.p.m.); (d) enzyme amount (% w/w) versus molar ratio of substrates (OA : TEA) (mole) on percentage conversion as response.
