RESUMEN
A new formulated product containing high yield of phytase from Schizophyllum sp., an important mushroom used for medicinal studies, was developed for application in feed industries and for future use in food processing. The enzyme presented a high activity yield 55.5 U/mL and 6240 U/gds in liquid and solid formulated product, respectively. It showed a good shelf-life in concentrated product, retaining 67.8 percent of its activity after 60 days of storage at room temperature and 90 percent of the activity was maintained in the liquid formulation after the same period. Powder bioformulated product maintained 77 percent of its activity after two months of storage, without the addition of chemical additives, which was named as a new bioformulated product containing high quantities of phytase. After separation and concentration steps, enzyme stability was monitored in two forms: liquid and solid. The liquid product was stable with the presence of manitol and polyethylene glycol at 1 percent (w/v), while solid product was the most stable product without the presence of chemical additives.
