Evaluation of long-term stability. Reactions were performed with purified enzymes after the test, using 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid), ABTS, as substrates in the parameters set with optimum enzymatic activity (pH 4.0 and 37 °C). The tests were performed with 3 replicates. The small letters at the top indicate the significant difference between each condition performed in the experiment, according to ANOVA and Tukey test at 5% probability
