BACKGROUND Pretreatments are a prerequisite for enzymatic hydrolysis of biomass and production of ethanol. They are considered to open up the plant cell wall structure by altering, moving or solubilizing lignin and hydrolyzing a proportion of hemicellulosic moieties. However, there is little information concerning pretreatment-induced changes on wheat bran cell wall polymers and indeed on chang...

Effects of the use of 200 g of either wheat bran, sugar beet pulp, soya bean hulls or alfalfa meal per kilogram diet on the digestive process of the weaned piglet were studied on 24 Duroc Landrace male piglets, weaned at 28 days of age. Piglets had an initial mean live weight of 7.92( 1.1) kg and were randomly distributed in six successive blocks of four animals. The total tract apparent digest...

Bulk in the distal colon provides protection against a range of large bowel disorders, but a simple standardized measure of the relative bulking efficacy of foods, for use in dietary management of distal colonic bulk, has not been available. This paper describes a faecal bulking index (FBI) for standardized measurement of the relative colonic bulking efficacy of foods relative to a reference ma...

spawn quality plays an important role in successful production of medicinal mushrooms. in this study, firstly, to determine the optimum temperature for mycelia growth of g. lucidum, four basal media, including seeds of wheat, barley, millet and abies sp. wood chip were studied separately at 25±1˚c and 29±1˚c. in the second section, in order to achieve suitable the mycelia growth, barley, wheat ...

HIGHLIGHTS The dephytinized wheat bran reduced the specific volume of bread samples compared with bran. hardness and chewiness values were increased, springiness cohesiveness decreased raise in rate storage. Sensory analysis revealed that addition or up to 5% was acceptable.

1. Four groups of adult male Sprague-Dawley rats were fed for 6 weeks on a diet with a low-fat content (50 g/kg) and another four groups were given a diet rich in fat (250 g/kg) and cholesterol (12 g/kg). In both cases, the basal diets were either fibre-depleted or supplemented with cellulose (60 g/kg), wheat bran (100 g/kg) or low-methoxyl pectin (100 g/kg). 2. Low-methoxyl pectin displayed th...

Biosorption of dyes by lignocelluloses may be an effective method for removing dyes from textile effluents. However, the resulting dyeadsorbed lignocellulosic materials may constitute another pollution problem. An integrated method can solve this problem. Here, various lignocelluloses were tested for their Astrazon Black and Astrazon Blue dyes removal activities. The dye adsorbed after 30 min c...

Improving the nutritional profile of sausages through the addition of dietary fiber might affect appetite, sensory characteristics, and liking differently depending on the fiber source. This study investigates the sensory characteristics and consumer acceptance of sausages with 10% (w/w) fat and added rye or wheat bran. Sensory descriptive attributes (odor, appearance, texture, and flavor) of r...

Bacterial strain Bacillus tequilensis BT21 isolated from marine sediments was found to produce extracellular xylanase. The xynBT21 gene encoding xylanase enzyme was cloned and expressed in Escherichia coli. The gene encoded a protein consisting of 213 amino acid residues with calculated molecular mass of 23.3 kDa. Purified recombinant xylanase had optimum activity at 60 °C and pH=6. The enzyme w...
