Effective fractionation of microalgae biomass as an initial step for its utilization as a bioenergy feedstock

چکیده
• S. obliquus was effectively fractionated by mild (un)catalyzed hydrothermal processes. Soluble sugars were mainly present as soluble oligosaccharides. Protein retained in the solid fraction. Dilute acid hydrolysis allowed higher oligosaccharides yield at conditions. Co-production of added-value marine biorefineries. Scenedesmus , a biotechnologically recognized microalga, grown 70 L vertical photobioreactors using non-supplemented secondary brewery wastewater culture medium. Upon collection, mechanical means, cells subjected to (autohydrolysis) and dilute (0.5% sulfuric acid) pre-treatments carried out pressure micro-reactors under isothermal conditions up 300 min. Both processes enabled high recovery (?50%) that were, great majority, oligomeric form (92% 90.5% for autohydrolysis hydrolysis, respectively). solubilization also presented relevant yields (35% removal), with allowing both protein productivities milder temperature. As compared current whole microalgae biomass-based upgrade strategies, use these is extremely promising, they will enable future co-production oligosaccharides, protein, which can be co-products biofuels-based biorefinery.

A Saponification Method for Chlorophyll Removal from Microalgae Biomass as Oil Feedstock
Microalgae oil is an optimal feedstock for nutraceutical, pharmaceutical and biodiesel production, but its high levels of chlorophyll limit its large-scale application. To date, few effective approaches have been developed to remove chlorophyll from microalgae oil. The main purpose of this study was to present a preprocessing method of algae oil feedstock (Scenedesmus) to remove chlorophyll by ...

متن کاملCarbohydrate and lignin partitioning in switchgrass (Panicum virgatum L.) biomass as a bioenergy feedstock
Approaching switchgrass (Panicum virgatum L.) as a multifunctional energy plant, it is important to comprehensively study the composition and partitioning of organic substances in the biomass. The character of carbohydrates and lignin concentration variation was assessed in switchgrass biomass cut at two maturity stages (heading and seed filling) in the first and second harvest years. Quality c...
