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...

A field experiment was conducted at the Experimental Farm of the Faculty of Agriculture, South Valley University at Qena on sandy soil to study the effect of integrated nutrient management (INM) on productivity and grain protein content of wheat. Seven different treatments with three replications each were carried out in the plot in RCB design. The recommended NPK, FYM and biofertilizer (Azotob...

using mulch to decrease and optimize water use, increase yield and fruit quality is known as a practical method. for this purpose, a split-factorial experiment based on complete block design with three replications on two melon cultivars was conducted in torbat-e-jam, iran. interval irrigation treatments in three levels (six, eight and 10 days) were considered as main plot and mulch (rice straw...

The study was carried out to determine the effects of optimum cultureconditions (substrate to water ratio, incubation period and salt concentrations, e.g. MgSO4.7H2O, CaCl2, KH2PO4 and urea) to increase the nutritive value of wheat straw (WS) by solid-state fermentation (SSF) with Arachniotus species. The performance of SSF product was evaluated in terms of favorable change in the crude protein...

The xylanase biosynthesis is induced by its substrate-xylan. The high xylan content in some wastes such as wheat residues (wheat bran and wheat straw) makes them accessible and cheap sources of inducers to be mainly applied in great volumes of fermentation, such as those of industrial bioreactors. Thus, in this work, the main proposal was incorporated in the nutrient medium wheat straw particle...

The research evaluated the interactions of two main factors (strain / types of spawn) on various parameters with the purpose to assess its effect on yield and biochemical composition of Lentinula edodes fruiting bodies cultivated on pasteurized wheat straw. The evaluation was made with four strains (IE-40, IE-105, IE-124 and IE-256). Different types of spawns were prepared: Control (C) (millet ...

Oak woodchips, used for production of shiitake Lentinula edodes (Berk) Pegler, are increasingly difficult to obtain due to dwindling supplies. We investigated the effect of adding ground wheat straw as a substitute for portions of oak woodchips in substrate formulae on mushroom yield and size. We also determined the effect of mushroom cropping on relative feed value (RFV) by chemical analysis o...

This paper emphasizes the experimental and numerical study of new cob mixes used for insulation load bearing wall elements. The provides complete datasets thermal properties walling materials, using with density ranging from 1107 kg/m3 to 1583 structural walls less than 700 kg m−3 walls. Various French soils fibres (reed, wheat straw, hemp shiv, flax straw) different water contents are studied....

Acrylonitrile was graft polymerized onto ground, water-washed wheat straw using Fe2 +-H 20 2 as initiator. Reaction conditions were selected to minimize homopolymer formation and ma.xi.mize the amount of polyacrylonitrile (PAN) grafted to straw. Polymerizations typically yielded straw-g-PAN containing 30-35% PAN. A two-step fractionation scheme was developed for determining the relative amounts...

BACKGROUND Low cost of raw materials and good process yields are necessary for future lignocellulosic biomass biorefineries to be sustainable and profitable. A low cost feedstock will be diverse, changing as a function of seasonality and price and will most likely be available from multiple sources to the biorefinery. The efficacy of the bioconversion process using mixed biomass, however, has n...
