S. Backlund et al., CHARACTERIZATION OF LECITHIN-BASED MICROEMULSIONS USED AS MEDIA FOR ACHOLESTEROL OXIDASE-CATALYZED REACTION, Colloid and polymer science, 272(9), 1994, pp. 1098-1103
Microemulsions stabilized by soybean lecithin and ethanol have been ch
aracterized with respect to phase behavior, distribution of the ethano
l cosolvent, conductivities, viscosities, and volume fractions of the
different phases in Winsor III systems. The conductivities and viscosi
ties of the surfactant-rich phase in the Winsor III system indicate th
at this phase exhibits a bicontinuous structure. The reaction yield at
298.2 K for the enzymatic conversion of cholesterol to cholestenone b
y cholesterol oxidase performed in a Winsor III system containing wate
r, lecithin, hexadecane, and ethanol is low.
