Scanning electron microscopy of filter paper after being treated by different solutions. Pictures with two different scale markers were taken at × 500 and × 2500 magnifications. a, c Filter paper treated by BSA in 50 mM acetic acid–sodium acetate buffer (pH 5.0) with different magnification. b, d Filter paper treated by Pp-ArCel5 in 50 mM acetic acid–sodium acetate buffer (pH 5.0) with different magnification. The final concentration of filter paper with 40 g/L was incubated in 50 mM acetic acid–sodium acetate buffer (pH 5.0), containing 0.5 g/L Pp-ArCel5 or BSA at 55 ℃ for 24 h
