Raw SCB was provided by the Qianwu sugar refinery plant in
Zhuhai, Guangdong, China. It was air-dried and placed at room
temperature in woven bags. The raw SCB was milled by a hammer
milling machine to get the particles between 0.15–0.27 mm. Xylan
was extracted by 12% (w/v) NaOH solution at a solid loading of 5%
under room temperature overnight (Jayapal et al., 2013). The liquid
fraction was separated by filtering through a 500-mesh filter cloth.
The solid fraction was washed by using tap water until pH 6–7. The
XRSB with moisture content of 74% was stored at 4C till
utilization
