Stimulatory Effect of Ferulic Acid on the Production of Extracellular Xylanolytic Enzymes by Aspergillus kawachii

Abstract

Production of extracellular β-1,4-xylanase, α-L-arabinofuranosidase, feruloyl esterase, and acetyl xylan esterase from Aspergillus kawachii was higher in a culture supplemented with ferulic acid than in a counterpart. Culture supernatant grown on oat spelt xylan supplemented with ferulic acid exhibited an increase in ferulic acid-releasing activity from insoluble arabinoxylan relative as compared to that from the ferulic acid-free culture.
