dc.description.abstract
Production of xylanase enzyme by fungi strains has gained interest in the recent years due to its high productivity, high catalytic power, as well as its potential applications in different areas such as feed, food, textile, and biofuel industries. The conventional methodologies, to produce enzymes, involve complex apparatus and chemical solvents and are associated with high costs and low-yield recovery. To obtain the high-yield recovery of the enzymes, modern enzyme extraction methods are taken into account. Aqueous two-phase systems (ATPS) are an alternative separative methodology for the purification and recovery of the enzymes and other biomolecules. The advantages of ATPS are easy scale-up and extraction, volume reduction, and rapid separation. The objective of this study was to produce Trichoderma harzianum xylanase by solid-state fermentation (SSF) using corn cobs as a support/substrate and employing ATPS for its partial recovery. In this study, the results showed the ability of a microorganism to grow on the corn cobs and to produce the xylanase enzyme. Xylanolytic activity reached 7.85 U/g of corn cobs. The enzyme was efficiently concentrated by ATPS. In addition, a high purification factor (10-fold) and considerable enzyme recovery (%ER) (84%) percentage were obtained.
