Overview

This study compares two types of solvents in improving cellulose enrichment and digestibility of rice straw, highlighting effective pretreatment methods.

Key Points

  • Choline chloride:formic acid pretreatment increased cellulose content to 58.4%, outperforming other solvents.
  • A delignification efficiency of 51.6% was achieved with ChCl:FA compared to lower efficiencies of 30.4% and 36.1%.
  • Spectroscopic and thermogravimetric analyses confirmed structural alterations in the rice straw after pretreatment.
  • The glucose yield from ChCl:FA pretreated samples reached 79.7% after hydrolysis, indicating superior digestibility.
