“…In A. melanoxylon, they are similar to those reported by López (2007), both average values and the range of variation. In eucalyptus, Lienqueo et al (2016) obtained slightly higher polyoses content values than those recorded in this study, using the same saccharification and fermentation simultaneous procedure.…”

Cellulosic ethanol is one of the most important biotechnological products to mitigate the consumption of fossil fuels and to increase the use of renewable resources for fuels and chemicals. Short rotation woody crops (SRWC) have been proposed as the most promising raw material for cellulosic ethanol production, as a result of its several advantages over traditional crops. In order to analyze the potential as crops for lignocellulosic bioethanol production in Chile, SRWC were established with the following species: Acacia melanoxylon, Eucalyptus camaldulensis, Eucalyptus globulus and Eucalyptus nitens. These crops were established in two contrasting environments and in three plantation densities. The average theoretical ethanol yield at 48 months reached 395.9 L . t -1 for A. melanoxylon, 348.7 L . t -1 for E. camaldulensis, and 363.9 L t -1 for E. nitens. It can be concluded that there are significant differences in polysaccharides yield between species and time. On the other hand, significant differences were found between environments.In conclusion, this study has shown that the choice of SRWC species used as a source of polysaccharides must take into account the percentage content in biomass and, crucially, the species, planting density, harvest cycle and site must be carefully selected to ensure a high biomass yield per unit area. POTENCIAL DE BIOETANOL DE CULTURAS LENHOSAS CONDUZIDAS EM ALTA DENSIDADE E CURTA ROTAÇÃO EM TERRAS MARGINAIS NO CHILE CENTRALRESUMO: Etanol celulósico é um dos mais importantes produtos biotecnológicos para reduzir o consumo de combustíveis fósseis e a aumentar a utilização de recursos renováveis para combustíveis e produtos químicos. Culturas lenhosas de curta rotação (CLCR) têm sido propostas como a mais promissora matéria prima para produção de etanol celulósico, devido às suas várias vantagens sobre culturas tradicionais. Para analisar o potencial de culturas para produção de bioetanol lignocelulósicos no Chile, CLCR foram estabelecidos com as seguintes espécies: Acacia melanoxylon, Eucalyptus camaldulensis, Eucalyptus globulus e Eucalyptus nitens. Estas culturas foram estabelecidas em dois ambientes contrastantes e em três densidades de plantio. O rendimento teórico médio de etanol em 48 meses atingiu 395,9 L . t -1 para A. melanoxylon, 348,7 L . t -1 para E. camaldulensis e 363,9 L . t -1 para E. nitens. Foi concluído que existem diferenças significativas no rendimento de polissacarídeos entre as espécies e o tempo. Por outro lado, foram encontradas diferenças significativas entre ambientes. Em conclusão, este estudo mostrou que a escolha da espécie usada na CLCR como fonte de polissacarídeos deve levar em conta sua percentagem na biomassa e, crucialmente, a espécie, densidade de plantio, ciclo de colheita e sítio devem ser cuidadosamente selecionados para garantir um rendimento elevado de biomassa por unidade de área.

“…The goal of this step is to remove the hemicellulose and lignin barrier around the cellulose fibres and to open the crystalline structure of the cellulose, making the cellulosic fibres more accessible to enzymatic attack (Bouza et al, 2016;Mosier et al, 2005). Physical, biological, chemical, and physicochemical strategies can be used (Lienqueo et al, 2016).…”

“…resulted in a maximum glucose yield of 82.2% wt. 46 In summary, the compositional analysis and saccharication data show that increasing the temperature from 120 C to 150 C can lead to pulps with a high cellulose content, no hemicelluloses and small quantities of lignin and with high enzymatic digestibility; all of these with a reduction in the pretreatment time, which may lead to signicant savings in the capital cost of the pretreatment reactor. Optimisation of pretreatment conditions will be required to prevent excess overtreatment and maintain a high pulp quality.…”
