“…Recently, there has also been an increasing interest of using lignocellulosic biomass from poplars and willows as raw material for conversion into biofuels such as biogas and bioethanol [3,6,7]. To improve the yields of biofuel as well as to understand the recalcitrance of the cell wall and pre-treatments to break the structure, intensive studies have been conducted in recent years (reviewed by [8,9]). Natural variant screening has also been carried out in different species, revealing the genetic variation in biomass chemical traits that are thought to be important for recalcitrance, e.g., [10,11].…”

An increasing interest to convert lignocellulosic biomass into biofuels has highlighted the potential of using willows for this purpose, due to its fast growth in short rotation coppice systems. Here, we use a mapping population of 463 individuals of a cross between Salix viminalis and S. viminalis × S. schwerinii to investigate the genetic background of different wood chemical traits, information of importance for breeding towards different uses of wood. Furthermore, using a subset of the mapping population, the correlation between biogas production and chemical traits was investigated. The phenotyping of wood was carried by Furriertransformed-Infrared spectrometry (FT-IR) and water content analysis. Quantitative trait loci (QTLs) analysis was used to identify regions in the genome of importance for the phenotypic variation of these chemical traits. We found 27 QTLs for various traits. On linkage group (LG) VI-1, QTLs for signals assigned to G-lignin, lignin, and the S/G ratio were collocated and on LG XIV we found a cluster of QTLs representing signals assigned to lignin, cellulose, hemicellulose, and water. The QTLs explained from 3.4 to 6.9% of the phenotypic variation indicating a quantitative genetic background where many genes influence the traits. For the biogas production, a positive and negative correlation was seen with the signals assigned to acetyl and lignin, respectively. This study represents a first step in the understanding of the genetic background of wood chemical traits for willows, information needed for complementary studies, mapping of important genes, and for breeding of varieties for biofuel production purposes.

“…The result of lignocellulose analysis in Table 1. showed that leaves contained 14-15% cellulose, 21-35% hemicellulose, 17-29% lignin, with a total potential of the hydrolyzable component to produce reducing sugars such as glucose and xylose 38-49%. makes the difference in characteristic leaf fiber, microfibril in the cell wall, pore structure on the cellulose surface and strong bond between cellulose, hemicellulose, and lignin in the crystallization zone than others [2]. In addition, these will increase the ability to block the accessibility reagent to cellulose and stability of cell walls.…”

“…The usage of agricultural waste, plantations, and forestry residues will minimize environmental impacts because they can be used as feedstocks for biofuel production or increase the valueadded chemical. Generally, hydrolysis process can convert dry plant biomass into reducing sugar in some ways, such as chemically [1], fermentatively [2], or enzymatically [3][4][5][6]. In previous research, Enzymatic hydrolysis of rice straw with pure or crude enzymes from Aspergillus niger and Trichoderma reesei, showed that hydrolysis in a batch process for seven hours more increased significantly reducing sugar concentration than the usage of commercial enzymes, but required time is too long [7].…”

“…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.
