Fig. 5From: Rapid estimation of sugar release from winter wheat straw during bioethanol production using FTIR-photoacoustic spectroscopyRegression coefficients from the prediction of glucose and xylose release. Spectral regions with a significant contribution in the prediction of glucose (a) and xylose (b) release during bioethanol production based on each of three subsets; top (subset 1), middle (subset 2), bottom (subset 3)Back to article page
