Rapid and simple assay for feruloyl and p-coumaroyl esterases
World Journal of Microbiology & Biotechnology, 1996A rapid, simple and sensitive method for detection of ferulic and p-coumaric acids using HPLC has been developed which can be used to determine the respective phenolic acid esterase activities of microorganisms. Prior concentration, purification or derivatization of the samples are not required. As little as 0.5 mg ferulic or p-coumaric acid/I could be

Feruloyl Esterase: A Key Enzyme in Biomass Degradation
Applied Biochemistry and Biotechnology, 2006Feruloyl esterase forms a part of the enzyme complex that acts collectively and synergistically to completely hydrolyze xylan to its monomers. The enzyme has found potential uses in a wide variety of applications of interest to the agrifood and pharmaceutical industries.

Hydrolysis of Nonpolar n-Alkyl Ferulates by Feruloyl Esterases
Journal of Agricultural and Food Chemistry, 2016Ferulic acid is one of the major phenolic acids in plants and can be found esterified to plant cell wall components, but also as long-chain n-alkyl and steryl esters. Microbial feruloyl esterases may play a role in the bioavailability of phenolic acids during human and animal digestion.

Microbial production, characterization and applications of feruloyl esterases
Process Biochemistry, 2007Feruloyl esterases (FAEs) act synergistically with xylanases to hydrolyze ester-linked ferulic (FA) and diferulic (diFA) acid from cell wall material and therefore play a major role in the degradation of plant biomass. The potential applications of these enzymes with reference to agriculture, food and pharmaceutical industries, are discussed in this ...

Feruloyl Esterase: A Principal Biodegradative Enzyme
2015Feruloyl esterases catalyse the hydrolysis of the substrate feruloyl-polysaccharide in order to yield ferulate and polysaccharide as the products. These enzymes play an important role in hydrolysis of the otherwise recalcitrant hemicellulose in the plant cell wall to its monomers.

AbstractThe feruloyl esterase (FAE) gene EST1 from the basidiomycete Pleurotus sapidus was heterologously expressed in Escherichia coli and Pichia pastoris. Catalytically active recombinant Est1 was secreted using P. pastoris as a host. For expression in P. pastoris, the expression vector pPIC9K was applied.

Bioresource Technology
Feruloyl esterase (FAE) has been extensively studied for its crucial auxiliary effect in the biodegradation of lignocellulose. In this study, a FAE database including 15,293 amino acid sequences was established to gain a better understanding of rumen FAEs through multi-omics analysis. The higher expression level of rumen fungal FAEs over bacterial FAEs

What can feruloyl esterases do for us?
Phytochemistry Reviews, 2009The role of feruloyl esterases in plant wall development, in gut health, and in the breakdown of plant biomass for the production of bioactive phytochemicals and biofuel is covered in this review. These enzymes have potential roles in stomatal cell function and the phenolic substitutions and cross-linkages between plant cell wall components.
