Xylanolytic enzymes are industrial biocatalysts with an increasing demand in the second – generation ethanol industry. Due to this, major advances in recent years regarding its cheaper and more efficient production from a lab - scale point of view have been developed; however, little has been investigated about the economic performance of these innovations after scale - up has taken place. In order to face this problem, the following research project comprises the design of a process to produce a high – xylanase activity enzymatic cocktail using sugarcane bagasse as a carbon source taking into account the kinetics of enzymatic secretion by Trichoderma harzianum P49P11 under fed - batch mode fermentation conditions, the scale – up of the unit operations required to perform the enzyme recovery by ethanol precipitation, the implementation of an optimal scheduling scheme and the project financial analysis. The process was designed from a design basis of 749 kg of sugarcane bagasse and resulted in a production capacity of 271 batches of 2.35 cubic meters of enzymatic cocktail per year. The product has a protein concentration of 15.13 g/L, a xylanase enzymatic activity of 485.67 U/mL and a unit production cost of US$ 38.21 per liter. This project resulted in a NPV of US$ 16.16 MM and an IRR of 27.71%, which confirmed that the designed process is technically and economically feasible.
