The thermostability of enzymatically pretreated bleached kraft pulp (BKP) fiber after sonication process.

Sample	Ti (°C)	Tmax (°C)
Control	303.4 ± 1.3	346.9 ± 0.5
EG	289.8 ± 0.5	340.4 ± 0.8
EG + AA9	300.5 ± 2.1	347.7 ± 1.9
EG + EX	293.5 ± 0.9	341.9 ± 1.8
EG + EX + AA9	302.4 ± 1.1	348.3 ± 2.2

EG: endoglucanase; AA9: lytic polysaccharide monooxygenase auxiliary activity family 9 enzyme; EX: endoxylanase. The experiment were performed in triplicate and the mean values and errors bars were calculated. The statistical analysis showed that the difference were statistically significant (one way ANOVA, p < 0.05).
