Fusarium solani cutinase supported on Chromosorb P was used to catalys
e transesterification and hydrolytic reactions of short volatile alcoh
ols and esters in a continuous gas/solid bioreactor. We showed that it
was of great importance to take into account the thermodynamic activi
ty of each chemical species present in the system, related to the effe
ctive availability of the substrates (and/or products).
