Identification and Characterization of Feruloyl Esterases Produced by Probiotic Bacteria

Phytochemicals in quinoa and amaranth grains and their antioxidant, anti‐inflammatory, and potential health beneficial effects: a review

“…While many of these enzymes are known to be secreted by different colonic bacteria of humans e.g. probiotics of the Lactobacillus and Bifidobacterium genera , using these enzymes to liberate bound phenolics is generally less effective as acid and alkaline hydrolyses. Various novel techniques including ultrasound‐assisted, microwave‐assisted, supercritical fluid and accelerated solvent extraction have been developed for increased extraction efficiency of phenolic compounds; however, it is not known if these physical actions are sufficient in breaking the ester or ether bonds of bound phenolics .…”

The role of ferulic acid esterase in the growth of Lactobacillus helveticus in the presence of phenolic acids and their derivatives

“…The ability to synthesize FaE by intestinal microflora is the first step in the extensive biotransformation of phenolic compounds in the intestine leading to an increase in their intestinal adsorption and bioavailability. a thorough discussion of the characteristics and biological role of FaEs can be found in the review by lai et al [23]. also, Sánchez-Maldonado et al [17] detected the decarboxylation and/or reduction in phenolic acids (chlorogenic, caffeic, p-coumaric, ferulic and protocatechuic acids) by Lb.…”
