advances on the processing of jatropha curcas towards a Whole Crop Biorefinery
Renewable & Sustainable Energy Reviews, 2016Co-Authors: Freddy S Navarropineda, Sergio A Bazrodriguez, Robert M Handler, Julio C SacramentoriveroAbstract:Abstract Jatropha is still considered a strong candidate for the production of second generation biofuels, despite recent large-scale failures worldwide to achieve high and consistent seed yields on the field. A short term alternative for making jatropha-based businesses profitable under current modest seed yields is by harnessing the Whole biomass under a Biorefinery concept, using state-of-the-art technology. Several studies have explored various ways to harness the jatropha biomass as feedstock for diverse processes such as densification, pyrolysis, carbon activation, gasification, combustion, anaerobic digestion, fermentation, solid-state fermentation, and extraction and purification of compounds. In this review we consolidate the publicly available information and present an analysis of what seems the best way to integrate these processes under a Biorefinery concept. A concrete proposal of a state-of-the-art jatropha-based Whole-Crop Biorefinery is made, together with recommendations of further research required to fill the gaps that may lead to even more profitable jatropha-based Whole-Crop Biorefinery systems.

centrifugal partition chromatography in a Biorefinery context separation of monosaccharides from hydrolysed sugar beet pulp
Journal of Chromatography A, 2015Co-Authors: David Ward, Max Cardenasfernandez, Peter Hewitson, Svetlana IgnatovaAbstract:A critical step in the bioprocessing of sustainable biomass feedstocks, such as sugar beet pulp (SBP), is the isolation of the component sugars from the hydrolysed polysaccharides. This facilitates their subsequent conversion into higher value chemicals and pharmaceutical intermediates. Separation methodologies such as centrifugal partition chromatography (CPC) offer an alternative to traditional resin-based chromatographic techniques for multicomponent sugar separations. Highly polar two-phase systems containing ethanol and aqueous ammonium sulphate are examined here for the separation of monosaccharides present in hydrolysed SBP pectin: l-rhamnose, l-arabinose, d-galactose and d-galacturonic acid. Dimethyl sulfoxide (DMSO) was selected as an effective phase system modifier improving monosaccharide separation. The best phase system identified was ethanol:DMSO:aqueous ammonium sulphate (300gL(-1)) (0.8:0.1:1.8, v:v:v) which enabled separation of the SBP monosaccharides by CPC (200mL column) in ascending mode (upper phase as mobile phase) with a mobile phase flow rate of 8mLmin(-1). A mixture containing all four monosaccharides (1.08g total sugars) in the proportions found in hydrolysed SBP was separated into three main fractions; a pure l-rhamnose fraction (>90%), a mixed l-arabinose/d-galactose fraction and a pure d-galacturonic acid fraction (>90%). The separation took less than 2h demonstrating that CPC is a promising technique for the separation of these sugars with potential for application within an integrated, Whole Crop Biorefinery.
