  1. Each data were averages of two independent experiments ± SD.
  2. 1Regenerated biomass = (mass of dried and regenerated biomass)/(mass of initial dried biomass) × 100 (%).
  3. 2Cellulose recovery = (mass of cellulose in dried and regenerated biomass)/(mass of initial cellulose) × 100 (%).
  4. 3Lignin recovery = (mass of lignin in dried and regenerated biomass)/(mass of initial dried lignin) × 100 (%).
  5. 4Cellulose content = (mass of cellulose in dried and regenerated biomass)/(mass of dried and regenerated biomass) × 100 (%).
