“…Charcoal detoxification of hydrolyzates was carried out by contacting hydrolyzates and charcoal (mass ratio: 10 g g -1 ) at room temperature under stirring for one hour (Rivas et al, 2002). The liquid phase was recovered by filtration and used for making culture media.…”

“…In general, lignin content is relatively small, comprising 12% to 35% of the biomass. Lignin is composed of heavily cross-linked polysaccharides, which makes it highly stable (Skoog and Hahn-Hagerdal 1988;Rivas et al 2002). Cellulose is the dominant fraction, accounting for 35% to 50% of the dry weight of biomass, while hemicellulose accounts for 20% to 50% (Kumar et al 2008).…”

“…leading to the release of sugar oligomers, xylose and arabinose and other chemicals. These compounds can be used for a variety of applications in the chemical, pharmaceutical and food industries, and also as fermentation media for the production of substances such as ethanol fuel and xylitol (Rivas et al, 2002). The solid fraction from the hydrothermal process contains lignin and cellulose and can be employed as raw material for alcohol production, ruminant feed, raw material for pulp and paper making and for energy production.…”

Abstract:Wood from the leguminous tree, Leucaena diversifolia, was subjected to hydrothermal treatment (autohydrolysis) at 160 to 180 ºC and 0 to 30 min. followed by ethanol-soda-anthraquinone delignification. The liquid phase contained 18.65 g of sugars per liter, and the solid phase had a gross heating value of 19.083 MJ/kg, but could also be uses as a source of cellulose pulp for the production of paper with tear, burst and tensile indexes of 2.4 Nm2/kg, 2.6 MPam2/kg and 40.7 KNm/kg respectively. Leucaena diversifolia lends itself readily to valorization for energy production, and also to integral, fractional exploitation by autohydrolysis and ethanol-soda-anthraquinone delignification, which can additionally bring environmental benefits to cropping zones. Reviewers' comments:Please make the following modifications to shorten the manuscript and to remove wording and typographical errors:1. Modify title: Integral valorization of Leucaena diversifolia by hydrothermal and pulp processing.The title has been changed.2.

[Add concluding sentence as to the importance/utility of your study.]The abstract has been modified and summarized 3. Shorten Introduction: Leucaena diversifolia is a leguminous tree that can grow 6-20 m tall and is adapted toMediterranean conditions. The tree produces large around 70 tons/ha/year of biomass (ref?) and possesses a high re-sprouting ability. It fixes nitrogen in symbiosis with Rhizobium sp. And thus improves soil fertility and has been exploited for soil conservation and consolidation (Goel and Behl, 2002). Moreover, Leucaena produces hard and strong wood and high-quality forage. Lignocellulosic biomass such as that obtained from L. diversifolia can be converted to useful fractions through "biorefining" (Clark et al., 2011). One refining strategy involves treatments that hydrolyze some of the polysaccharides within the biomass. Hydrothermal treatment causes the total or partial dissolution of hemicellulses as the hydrolysis of acetyl groups gives rise to acetic acid which in turn catalyzes the hydrolysis of the polysaccharide (reference?) leading to the release of sugar oligomers, xylose and arabinose and other chemicals. These compounds can be used for a variety of applications in the chemical, pharmaceutical and food industries, and also as fermentation media for the production of substances such as ethanol fuel and xylitol (Rivas et al., 2002). The solid fraction from the hydrothermal process contains lignin and cellulose and can be employed as raw material for alcohol production, ruminant ...
