|Title:||Enzymatic synthesis of isoamyl ester in aqueous media optimization using a central composite design|
|Abstract:||Catalytic action of two non-commercial lipases (E.C. 18.104.22.168) during isoamyl acetate synthesis in a solvent-free system was tested using experimental design to better understand relationship between reaction variables. Yields ranging from 67 to 77% molar conversion were achieved. Synthesis of isoamyl acetate catalyzed by the chosen lipase (Rhizopus sp.) was optimized, to maximize the molar conversion (yield, Y) in a solvent-free system. Response surface methodology involving substrate molar ratio (RM) and amount of lipase (L) was used, and a second-order model was employed to generate response surfaces. Optimum conditions to obtain Y max = 80% were: RM= (2: 1), L= 8.7% (w/w), 40degreesC, and 48 hr of reaction time.|
