Mass balance flow chart of Miscanthus biomass for bioethanol (on a 100 g basis) among three optimal pretreatments, simultaneous saccharification, and fermentation process. a LHW pretreatment of Mlu26 Miscanthus sample; b H₂SO₄ (purity: 98%) pretreatment of Mlu26 Miscanthus sample; c NaOH pretreatment of Mlu11 Miscanthus sample. Mass amount of insoluble wall polymers (cellulose, hemicelluloses, and lignin) are presented in streams 1 and 3. Mass amount of soluble sugars (hexoses and pentoses) and ethanol yield are presented in streams 2, 4, and 5
