9. Potencialidad de varias especies para la obtención de biomasa con fines energéticos en el secano mediterráneo de Chile
Abstract In Chile, there are about 1.8 million hectares of dryland soils with severe site restrictions for agronomic and forest species growth. However, these soils can be used to establish energy crops, using forest species specially adapted to this condition. The purpose of this paper is to estimate the potential land availability in the drylands of centra

11. ELEPHANT GRASS (Pennisetum purpureum Schumach) IS A PROMISING FEEDSTOCK FOR ETHANOL PRODUCTION BY THE THERMOTOLERANT YEAST Kluyveromyces marxianus CCT 7735
ABSTRACT Elephant grass (Pennisetum purpureum Schumach) is regarded as a promising feedstock for second generation ethanol production, due to its high cellulose content, biomass production and rapid growth. The yeast Kluyveromyces marxianus CCT 7735 is capable of producing ethanol from agroindustrial residues, such as lignocellulosic biomass. Therefore, this
