Recent years have seen an increase in the use of lignocellulosic materials in the development of bioproducts. Because sisal fiber is a low cost raw material and is readily available, this work aimed to evaluate its hemicellulose fraction for the simultaneous production of xylitol and ethanol. The sisal fiber presented a higher hemicellulose content than other frequently-employed biomasses, such...

the aim of this study was to evaluate the effects of chemical treatments including urea (5%), ammonia (3.5%), calcium hydroxide (4%), sodium hydroxide (5%), sulphuric acid (5%) and hydrogen peroxide (5%) on ph, dm solubility, lignin, silica, phenolic compounds, cellulose and hemicellulose stucture and ruminal degradability of rice straw. after processing, the treated straw was ensiled for 1 mon...

The pyrolysis characteristics of sugarcane bagasse hemicellulose were investigated using a tubular furnace. The total gas yield and the releasing behavior of the main gas products were measured by GC analysis. The liquid products were analyzed by GC-MS and ion chromatography. The chars were investigated by elemental analysis and proximate analysis. The volatile remaining in the char extracted b...

Thermophilic Geobacillus spp. can efficiently hydrolyze hemicellulose polymers and are therefore of interest in biotechnological applications. Here we report the genome sequences of two hemicellulolytic strains, Geobacillus sp. CAMR12739 and CAMR5420.

BACKGROUND Current single-stage delignification-pretreatment technologies to overcome lignocellulosic biomass recalcitrance are usually achieved at the expense of compromising the recovery of the polysaccharide components, particularly the hemicellulose fraction. One way to enhance overall sugar recovery is to tailor an efficient two-stage pretreatment that can pre-extract the more labile hemic...
