Disruption of BsEXLX1 on cellulose. Avicel PH-101 was incubated in 50 mM sodium acetate buffer (pH 4.8) with different concentrations (5, 10, 25, 50, and 100 ppm) of BsEXLX1 for 72 h at 45 °C with agitation (150 rpm). a FTIR spectra of BsEXLX1-treated and untreated Avicel PH-101. The bands at 897 and 2915 cm⁻¹ were used for normalization. b Solid-state NMR spectra of BsEXLX11-treated and untreated Avicel PH-101. c Abs(897)/Abs(2915) in FTIR and solid-state NMR spectra. d Disruptive effect of BsEXLX1 at different concentrations on CrI and specific surface area. e XRD patterns of BsEXLX1-treated and untreated Avicel PH-101
