    The hydrolysis of nitriles into the corresponding carboxylic acids usually requires harsh acidic or basic conditions, which can lead to unwanted by-products. Enzymatic hydrolysis by nitrilases is an interesting alternative that tolerates fragile functional groups.



    We have extended the diversity of known nitrilases and established their substrate profile.1,2 Particularly robust nitrilases are used immobilised in microfluidic systems (LETI and LITEN collaboration, CEA Grenoble).3,4
