“…The results obtained by applying the hydrothermal pretreatment were similar to those obtained for other biomass such as grape stalks, corn stalks, grass (Cynodon dactylon), sorghum, wood, olive tree prunings, eucalyptus, bamboo, wheat straw and sugarcane bagasse (Amendola et al, 2012;Egues et al, 2012;Lee et al, 2009;Rohowsky et al, 2013;Chen et al, 2010;Martin et al, 2010;Alves et al, 2010;Ruiz et al, 2013a;Ruiz et al, 2013b;Abril et al, 2012). Figure 2 shows the results of the morphological analysis of the raw material and solid fraction of the pretreated bagasse by SEM.…”

-Glucose production from sugarcane bagasse was investigated. Sugarcane bagasse was pretreated by four different methods: combined acid and alkaline, combined hydrothermal and alkaline, alkaline, and peroxide pretreatment. The raw material and the solid fraction of the pretreated bagasse were characterized according to the composition, SEM, X-ray and FTIR analysis. Glucose production after enzymatic hydrolysis of the pretreated bagasse was also evaluated. All these results were used to develop relationships between these parameters to understand better and improve this process. The results showed that the alkaline pretreatment, using sodium hydroxide, was able to reduce the amount of lignin in the sugarcane bagasse, leading to a better performance in glucose production after the pretreatment process and enzymatic hydrolysis. A good xylose production was also observed.

“…These pretreatments include dilute acid (Lloyd and Wyman 2005;Saha et al 2005;Schell et al 2003), hot water (Liu and Wyman 2004;Ruiz et al 2013), ammonia fiber expansion (Hoover et al 2014;Lau et al 2008;Murnen et al 2007), steam explosion (Grous et al 1986;Kaar et al 1998), lime (Chang et al 1997;Kim and Holtzapple 2005), organic solvent (Zhang et al 2007;Zhao et al 2009b), and pyrolysis and mechanical disruption (Mosier et al 2005). In all these treatments, the substantial degradation of lignin is accompanied by considerable reduction in fermentable sugar content of the feedstock, resulting in a loss of 20-35% of the mass of lignocellulose (Galbe and Zacchi 2007;Lee et al 2009).…”

Chemical and physical pretreatment of biomass is a critical step in the conversion of lignocellulose to biofuels and bioproducts. Ionic liquid (IL) pretreatment has attracted significant attention due to the unique ability of certain ILs to solubilize some or all components of the plant cell wall. However, these ILs not only inhibit enzyme activities, but also the growth and productivity of microorganisms used in downstream hydrolysis and fermentation processes.While pretreated biomass can be washed to remove residual IL and reduce inhibition, extensive washing is costly and not feasible in large-scale processes. IL tolerant microorganisms and microbial communities have been discovered from environmental samples and studies begun to elucidate mechanisms of IL tolerance. The discovery of IL tolerance in environmental microbial communities and individual microbes has lead to the proposal of molecular mechanisms of resistance. In this article, we review recent progress on discovering IL tolerant microorganisms, identifying metabolic pathways and mechanisms of tolerance, and engineering microorganisms for IL tolerance. Research in these areas will yield new approaches to overcome inhibition in lignocellulosic biomass bioconversion processes and increase opportunities for the use of ILs in biomass pretreatment.

“…One of the alternative processes for algal biomass containing large amounts of water up to 90% is the hydrothermal liquefaction and gasification. There are reviews concerning production of bio-oil and CH 4 /H 2 gasification, though hydrothermal process is a useful technology for algae (Yeh et al, 2013;Ruiz et al, 2013). Main challenge in hydrothermal treatment of algae is high salt content leading to corrosion and blockage salt precipitates.…”

Algal biomasses were tested as feedstock for steam gasification in a dual-bed microreactor in a two-stage process. Gasification experiments were carried out in absence and presence of catalyst. The catalysts used were 10% Fe2O3-90% CeO2 and red mud (activated and natural forms). Effects of catalysts on tar formation and gasification efficiencies were comparatively investigated. It was observed that the characteristic of algae gasification was dependent on its components and the catalysts used. The main role of the catalyst was reforming of the tar derived from algae pyrolysis, besides enhancing water gas shift reaction. The tar reduction levels were in the range of 80-100% for seaweeds and of 53-70% for microalgae. Fe2O3-CeO2 was found to be the most effective catalyst. The maximum hydrogen yields obtained were 1036cc/g algae for Fucus serratus, 937cc/g algae for Laminaria digitata and 413cc/g algae for Nannochloropsis oculata.FP7 Marie-Curie IAPP-Project (230598
