Industrial processes lead to high amounts of lignocellulosic wastes, that are not valorised properly. Feruloyl esterase are a group of accesory enzymes used in the biodegradation of lignocellulose, capable of releasing ferulic acid that is located either between lignin and hemicellulose or between hemicelluloses. The importance of feruloyl esterase is given mainly by the fact that its action allows other enzymes to hydrolyse xylan or lignin. The released ferulic acid has several applicatios in various industries such as food, feed, medical, biofuel, pulp and paper etc. Feruloyl esterases are produced by several microorganisms (bacteria or fungi), but research studies are still focused on finding more sources for these enzymes. There are different methods for detecting microbial strains able to produce feruloyl esterase, the most used being plate screening methods.
