X-ray diffraction spectra of raw and delignified pineapple leaf waste. Maximum delignification of pineapple leaf waste has been obtained at solid loading 25% (w/v), incubation time 5.30 h, 45 °C, pH 6.16 and enzyme concentration 582.82 (IU/mL). Change in cellulose crystallinity of laccase delignified substrate has been studied against the raw substrate
