Lipase Catalyzed Synthesis of D-xylose-based Biosurfactants and their Surface Properties
Abstract: Synthesis of a homologous series of 1-O-acyl xylose esters with long and very long acyl chains derived from fatty acids was performed via enzymatic esterification in one step using Candida antarctica lipase B. The effect of fatty acid chain length on the activity of the lipase was evaluate...
