Alkali pretreated of wheat straw and its enzymatic hydrolysis
The efficiency of enzymatic hydrolysis of cellulose can be improved by various pretreatments of the substrate. In order to increase the efficiency of enzymatic saccharification of the wheat straw, we determined the effect of different pretreatments on the physical structure, chemical components and enzymatic saccharification of wheat straw. Our results showed that combination of grinding and so...
متن کاملEffect of Cellobiase and Surfactant Supplementation on the Enzymatic Hydrolysis of Pretreated Wheat Straw
Wheat straw is a suitable raw material for ethanol production since it has high cellulose content. The objective of this work was to evaluate the effect of cellobiase and surfactant on the enzymatic hydrolysis of lignocellulosic materials. For this purpose, wheat straw was first pretreated by organosolv digestion. The chemical compositions of raw and pretreated wheat straw were analyzed. Much o...
متن کاملPulp properties resulting from different pretreatments of wheat straw and their influence on enzymatic hydrolysis rate.
Wheat straw was subjected to three different processes prior to saccharification, namely alkaline pulping, natural pulping and autohydrolysis, in order to study their effect on the rate of enzymatic hydrolysis. Parameters like medium concentration, temperature and time have been varied in order to optimize each method. Milling the raw material to a length of 4mm beforehand showed the best cost-...
متن کاملEffect of Laccase Dosage on Enzymatic Hydrolysis of Steam- Exploded Wheat Straw
When laccases are applied for detoxifying steam-exploded slurries, enzymatic hydrolysis is affected. In this study, 10% (w/v) of dry weight (DW) slurry or water insoluble solid fraction were subjected to 48 h enzymatic hydrolysis in the presence of different laccase loadings (0.1, 0.5, 5 or 10 IU/g DW). All laccase dosages higher than 0.1 IU/g DW significantly inhibited glucose recovery. Nevert...
متن کاملComparison of mechanistic models in the initial rate enzymatic hydrolysis of AFEX-treated wheat straw
BACKGROUND Different mechanistic models have been used in the literature to describe the enzymatic hydrolysis of pretreated biomass. Although these different models have been applied to different substrates, most of these mechanistic models fit into two- and three-parameter mechanistic models. The purpose of this study is to compare the models and determine the activation energy and the enthalp...
