Description:

Two lignocellulolytic accessory enzymes, feruloyl esterase D (FAED_SCYTH) and ß-xylosidase (XYL43B_SCYTH) were cloned and produced in the Pichia pastoris X33 as host. The molecular weight of recombinant enzymes FAED_SCYTH and XYL43B_SCYTH were ~ 31 and 40 kDa, respectively. FAED_SCYTH showed optimal activity at pH 6.0, 60 °C; and XYL43B_SCYTH at pH 7.0, 50 °C. FAED_SCYTH and XYL43B_SCYTH exhibited t1/2: 4 and 0.5 h, respectively (50 °C, pH 5.0). The ß-xylosidase was bi-functional with pronounced activity against pNP-a-arabinofuranoside besides being highly xylose tolerant (retaining ~ 97% activity in the presence of 700 mM xylose). Cocktails prepared using these enzymes along with AA9 protein (PMO9D_SCYTH) and commercial cellulase CellicCTec2, showed improved hydrolysis of the pre-treated lignocellulosic biomass. Priming of pre-treated lignocellulosic biomass with these accessory enzymes was found to further enhance the hydrolytic potential of CellicCTec2 promising to reduce the enzyme load and cost required for obtaining sugars from biorefinery relevant pre-treated substrates.
