Fig. 1From: Physical and chemical differences between one-stage and two-stage hydrothermal pretreated hardwood substrates for use in cellulosic ethanol productionDiagram of the process and the additional assays performed. The top row indicates process steps while the bottom row indicates various assays and experiments performed. Solid lines indicate the flow of the process while dashed lines indicate where samples were taken to perform subsequent assays. Note that the pretreatment box is one element and contains one pretreatment step for MS1112 and two pretreatment steps for MS1107Back to article page
