N2 - This paper describes a newly developed technique to adjust and control the water activity in enzymatic reactions in organic media. A saturated salt solution of known water activity is circulated inside a silicone tube, submerged into the reaction medium. The circulating solution can both absorb and release water. Water activity control during lipase catalyzed esterification was demonstrated with diisopropyl ether as solvent.
