Fig. 1From: Lipase-catalyzed biodiesel production and quality with Jatropha curcas oil: exploring its potential for Central AmericaEnzymatic biodiesel produced with Jatropha and palm oil. a The alkaline-catalyzed biodiesel produces a reddish-brown glycerol phase. b Enzymatic biodiesel catalyzed by CA produced a cleaner (white) glycerol phase. c Jatropha biodiesel catalyzed by TL. d Palm biodiesel produced with TL enzymatic catalyst. One advantage of enzymatic biodiesel over alkaline catalyzed biodiesel is a cleaner, higher-quality glycerine by-productBack to article page
