From: Assessing the molecular structure basis for biomass recalcitrance during dilute acid and hydrothermal pretreatments

Substrate Pretreatment conditions DP before pretreatment DP after pretreatment Reference
Corn stover DA pretreatment: 3% H2SO4, 180°C, 90 s 7300a 2700a [32]
Poplar DA pretreatment: 2% H2SO4, 190°C, 70 s 3500a 600a [32]
Loblolly pine DA pretreatment: 1% H2SO4, 180°C, 30 min 3642b 1326b [95]
Switchgrass DA pretreatment: 5% H2SO4, 180°C, 5 min 1891b 1342b [82]
Corn stover Hydrothermal pretreatment: 190°C, 15 min 7300a 5700a [32]
Poplar Hydrothermal pretreatment: 200°C, 10 min 3500a 1750a [32]
  1. a: DP was measured by viscometric method[96].
  2. b: DP was measured by gel-permeation chromatography (GPC) technique[97].
