Micro-reactors containing a monolith-immobilised thermophilic l-aminoacylase, from Thermococcus litoralis, have been developed for use in biotransformation reactions and a study has been carried out to investigate the stereospecificity and stability of the immobilised enzyme. The potential to use the developed micro-reactors as a tool for rapid screening of enzyme specificity was demonstrated, confirming that the l-aminoacylase showed a ...
