    • 12. Microemulsions containing lipase were prepared by stirring a mixture of PPL (0.25g) and reverse micellar solution of isooctane-water - AOT [sodium bis-(2-ethylhexyl) sulphosuccinate], which in turn was prepared by shaking a mixture of water (4ml), isooctane (25ml) and AOT (4.9 g). Gelatin (7g) was dissolved in water (10ml) preheated to 50°C and the above microemulsion containing enzyme was added to it with shaking while maintaining the temperature a little above 50°C, the gel transition temperature. The resulting microemulsion-based gels (MBGs) were subsequently cooled to room temperature and pelleted prior to use.

    • note
    • 16. The isolated yields of the products are much lower than the % of conversions of the substrates as it was quite difficult to remove gelatin from the reaction mixtures and several chromatographic operations had to be performed, followed by prep TLC/ crystallization to isolate the products in the pure form, we have not recovered the substrates. No by-product was observed to be formed during the course of these reactions.
