“…A variety of physical, chemical, and physicochemical pretreatment methods have been tested to overcome the recalcitrance of lignocellulose, improve enzyme efficiency, and increase the yield of sugars as described in several recent reviews (Kim et al 2016;Silveira et al 2015;Singh et al 2015;Zhang et al 2016). 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).…”

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.

“…Cellulose is a polysaccharide with β-1,4-glucoside bonds in a linear chain. The β-1,4-glycoside bond on cellulose fibers can be hydrolyzed to produce glucose monomers by acid or enzymatic hydrolysis but the existence of lignin composition make the conversion lignocelluloses to energy is costly and ineffective up to now [2,[11][12][13][14][15]. Besides that, differences of lignocelluloses composition make difference structure of biomass.…”

Abstract. Organic wastes from Swiettenia marcophylla L, Artocarpus heterophyllus L, Mangifera indica L, and Annona muricata L were prepared by grinding into 0.1875, 0.3750, 0.7500 mm of particle size and delignified by 2% NaOH at 80 o C for 90 minutes. Acid dilution hydrolysis process with H2SO4 1% was performed at 150 o C for 120 minutes in a closed reactor. The effect of particle size and delignification on and reducing sugar concentration were investigated. The result showed (1) leaves that can be used as raw material to produce hydrogen should have 38-49% cellulose and hemicellulose. (2) Reducing sugar concentration increased with particle size reduction and delignification. (3) the best result with the highest reducing sugar concentration was achieved by 0.1875 mm particle size with delignification on Annona muricata L.

“…Lignocellulosic biomass (complex polymer made up from three carbohydrates: cellulose and hemicellulose) is considered an attractive feedstock for the production of fuel ethanol due to its availability in large quantities at low cost and for reducing competition with food (Cardona and Sanchez, 2007;Cheng et al, 2008, Mandade et al, 2016Zhang et al, 2016) Second generation biofuels (e.g. lignocellulosic bioethanol), based on lignocellulosic biomass, are becoming a viable alternative.…”

The optimum alkali pretreatment parameters (reaction time, reaction temperature and potassium hydroxide concentration) for facilitate the conversion into fermentable sugar (glucose) from steam exploded (severity log Ro 2.45) barley husk were determined using Response Surface Methodology (RSM) based on a factorial Central Composite Design (CCD). The prediction of the response was carried out by a second-order polynomial model and regression analysis revealed that more than 88% of the variation can be explained by the models.The optimum conditions for maximum cellulose content were determined to be 201 min reaction time, 124℃ reaction temperature and 0.9% potassium hydroxide concentration. This data shows that the actual value obtained was similar to the predicted value calculated from the model. The pretreated barley husk using acid hydrolysis resulted in a glucose conversion of 94.6%. This research of steam explosion and alkali pretreatment was a promising method to improve cellulose-rich residue for lignocellulosic biomass.
