The researchers studied a green method to break down hemicellulose in corncob by reusing the hydrolysate. They looked at how reusing the hydrolysate affected the levels of d-xylose and l-arabinose. Over time, the concentrations of d-xylose and l-arabinose increased with each reuse. After the fifth time, the concentrations were 196.7 g·L− 1 for d-xylose and 22.0 g·L− 1 for l-arabinose. They found that a substance was produced during the reuse process that prevented the breakdown of d-xylose, which was confirmed by changes in d-xylose concentration and loss rate over time.
