Feruloyl esterases (FAE) are carboxylic esterases (EC 3.1.1) that cleave the bond between ferulic acid and L-arabinofuranosyl residues of arabinoxylans. These enzymes, in addition to helping the  econstruction of lignocellulosic biomass, have a natural capacity to synthesize a wide range of bioactive molecules with interesting properties (notably anti-oxidant) in the fields of food, pharmaceuticals or cosmetics.
Within the OPTIBIOCAT European project, a methodology to express, generate and screen diversity for Aspergillus niger feruloyl esterase A was developed, tested and implemented in a high-throughput fashion, using ad hoc chromogenic probes [1]. A total of ~10,000 mutant clones were generated and screened to isolate 13 mutants with improved thermal and/or solvent stability. The most interesting mutations were individually studied while their random recombination was performed in a second round of evolution through Staggered Extension Process (StEP) [2].
