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