Assessment of Durum Wheat (<i>Triticum durum</i> Desf.) Genotypes Diversity for the Integrated Production of Bioethanol and Grains

Wheat straw is an abundant source of lignocellulosic biomass that is generally not utilized for biofuel production, nor for other uses. Recent EU renewable energy directive fosters bioethanol production through lignocellulosic sugars fermentation, but the cost of this process is an issue that often...
