From Classical to High Throughput Screening Methods for Feruloyl Esterases: A Review.

Area of Science:

• Biochemistry
• Enzymology
• Industrial Biotechnology

Background:

• Feruloyl esterases (FAEs) are hydrolases that cleave ester bonds between plant cell wall polysaccharides and phenolic acids.
• FAEs are vital in biofuel, medicine, and food industries for synthesizing high-value molecules via esterification and transesterification.
• Despite extensive research on FAEs, few High Throughput Screening (HTS) assays have been reported.

Purpose of the Study:

• To provide a comprehensive review of classical and High Throughput Screening (HTS) methods for Feruloyl esterases (FAEs).
• To highlight the advantages and disadvantages of various FAE screening techniques.
• To suggest future research perspectives for FAE screening.

Main Methods:

• Review of literature on classical enzyme assays for FAEs.
• Analysis of reported High Throughput Screening (HTS) methods for FAE detection and characterization.
• Comparative evaluation of different screening strategies based on efficiency, cost, and substrate range.

Main Results:

• Classical FAE assays are often time-consuming and low-throughput.
• HTS methods offer increased efficiency and potential for large-scale enzyme discovery and characterization.
• Significant challenges remain in developing universally applicable and robust HTS assays for the diverse FAE family.

Conclusions:

• Effective screening methods are critical for advancing FAE research and industrial applications.
• Further development of HTS assays is needed to overcome current limitations.
• Future research should focus on novel assay development and optimization for broader FAE substrate specificities.
