Abstract：
:Here, we demonstrated the immobilization of bacterial feruloyl esterase (FAE) from Butyrivibrio sp. XPD2006, Lactobacillus crispatus, Butyrivibrio sp. AE2015, Ruminococcus albus, Cellulosilyticum ruminicola and Clostridium cellulovorans on SBA-15 and their ability to synthesize butyl ferulate (BFA). The BFae2 from Butyrivibrio sp. XPD2006 showed the best catalytic efficiency. High BFA yield was produced when the immobilization of BFae2 took place with a high protein loading and narrow pore sized SBA-15, suggesting alteration of enzyme behavior due to the crowding environment in SBA-15. Grafting of SBA-15 with octyl moieties led to shrinking pore size and resulted in 2.5-fold increment of BFA activity compared to the free enzyme and 70%mol BFA was achieved. The BFae2 encapsulated in hydrophobic-modified SBA-15 endured up to seven reaction cycles while the BFA activity remained above 60%. This is the first report showing the superior performance of hydrophobic-modified surface to entrap FAE to produce fatty phenolic esters.
