Abstract Hydrolysis of cellulose in concentrated phosphoric acid is known to give two distinctive mono-disperse cello-oligomers: the degree polymerization (DP) 7 and 15. To understand formation mechanism monodisperse cello-oligomers, transition DP during hydrolysis was monitored by size-exclusion chromatography combined with multiangle laser-light scattering analyses (SEC/MALLS). The obtained r...

Ammonia boron is one of the chemical compounds with high energy density that eliminates problem storing hydrogen, a clean source. borane (NH3BH3), hydrogen storage compounds; High capacity (19.6% H2 by mass) has very important place in fuel technology due to its stable structure aqueous solution. The main parameter determining ammonia hydrolysis, production efficiency and reaction course cataly...

Background: Cellulose is hydrolyzed to sugar monomers by the synergistic action of multiple cellulase enzymes: endo-β-1,4-glucanase, exo-β-1,4 cellobiohydrolase, and β-glucosidase. Realistic modeling of this process for various substrates, enzyme combinations, and operating conditions poses severe challenges. A mechanistic hydrolysis model was developed using stochastic molecular modeling appro...

Three different types of biomass sourced from forestry waste (eucalyptus residues), agricultural (wheat straw), and energy crop (miscanthus) were used as starting materials to produce hemicellulosic sugars, furans (furfural hydroxymethylfurfural), oligosaccharides. A two-step hybrid process was implemented; first autohydrolysed without any additive extract hemicelluloses dissolve it in water. T...

Papain is a cysteine endopeptidase of vegetal origin (papaya (Carica papaya L.) with diverse applications in food technology. In this review we have focused our attention on its application the production bio-peptides by hydrolysis proteins from fish residues. This way, residual material, that can become contaminant if dumped without control, converted into highly interesting products. The main...

Tensoactive species obtained by papain hydrolysis of soy protein were characterized structurally and physicochemically, and their foam-forming and -stabilizing capacity studied. Protein structural changes upon reaction ending were correlated with functional and interfacial properties and with the behaviour thereof with varying hydrolysis degree. Two different means of halting hydrolysis -pH red...

Native granular starches (corn, cassava,mung bean, and sago) were hydrolyzed using amixture of alpha-amylase and glucoamylase at 35 ◦C for 24h. Hydrolyzed starches were analyzed for the degree of hydrolysis and for physicochemical and functional properties. Corn starch showed the highest degree of hydrolysis, as evidenced by the presence of distinct pores penetrating deep into the granules. Enz...
