Abstract
The reactivity of Rhizopus delemar lipase immobilized in sodium bis(2-ethylhexyl) sulfosuccinate microemulsion-based organogels (MBGs) was investigated as a function of the water content in the gel. Gelatin was used as the gelling component of the MBGs. The maximal reaction rate of 6.5 μM s−1 was obtained at a WG (molar ratio of water to AOT in the MBG phase) value of 100. In the experimental WG conditions, the reaction proceeded under an effectiveness factor of 0.02 to 0.04 giving the reaction-limiting regime.
