A Fusarium solani pisi recombinant cutinase solubilized in phosphatidylcholine/isooctane reverse micelles was used to catalyse the esterification reaction of butyric acid with 2-butanol at pH 10.7. The influence of temperature, Wo and substrates on lipase stability was evaluated. The enzyme displays better stability, with a half-life over 125 days, at a temperature of 22 degrees C and for a low water content (Wo = 6.5). Butyric acid increased the cutinase deactivation (t1/2 = 0.56h), while 2-butanol led to a similar half-life (t1/2 = 14h) as without substrate.
