Rapid selection and identification of Miscanthus genotypes with enhanced glucan and xylan yields from hydrothermal pretreatment followed by enzymatic hydrolysis

Table 1 Summary of Miscanthus pretreatment data reported in the literature

Pretreatment		Overall conversion*, %		Ref.
Pretreatment		Glucan	Xylan	Ref.
ball-milling: NaCl/glacial acetic acid, 70°C, 1 h		100	90.6	[15]
ammonia fiber expansion: 60°C, 5 min		96	81	[16]
one step extrusion/NaOH: solid to liquid ratio of 1:6, NaOH 12%(w/w) pretreatment at 70°C for 4 h		69	38	[14]
ethanol organosolv process		98	73	[17]
diluted acid explosion: 0.75% H₂SO₄ at 100°C for 14 h; atmospheric air/H₂O₂ wet explosion with solid loading 15% at 170°C under 200 bar for 5 min	air	61.3	94.9	[18]
	H₂O₂	63.7	82.4	[18]
alkaline peroxide: (50°C, 24 h), electrolyzed water at 121°C for 50 min		84	N/A	[19]

* Overall conversion refers to total conversion resulted from pretreatment and sequential enzymatic hydrolysis on the basis of original glucan or xylan content of raw Miscanthus.
