Sugar beet pulp (SBP) is a waste product of the sugar industry which is rich in ferulic acid. Few ferulic acid esterases (FAEs) that are capable of releasing ferulic acid from SBP or from SBP soluble feruloylated oligosaccharides (SFO‐SBP) have been described. Streptomyces avermitilis CECT 3339 was grown in medium containing SBP or destarched wheat bran (DSWB) as the carbon source. FAE activity was evaluated in terms of the micro‐organism's capacity to release ferulic acid from DSWB, SBP, SFO‐DSWB and SFO‐SBP. S avermitilis showed FAE activity in both media and was able to release ferulic acid from DSWB, SFO‐DSWB and SFO‐SBP. A comparison of the FAE activity detected in each medium indicated that different activities were induced by each type of carbon source. © 1999 Society of Chemical Industry
