the importance of dietary fiber in normal and therapeutic diets has been acknowledged by numerous authors in recent years. dietary fiber has different physiological effects on human health. the recommended daily intake of dietary fiber is about 30 g, but less than this is often consumed. wheat bran is an excellent source of dietary fiber and is used to fortify foods. the nutritional benefits of...

BACKGROUND Thermobacillus xylanilyticus is a thermophilic and highly xylanolytic bacterium. It produces robust and stable enzymes, including glycoside hydrolases and esterases, which are of special interest for the development of integrated biorefineries. To investigate the strategies used by T. xylanilyticus to fractionate plant cell walls, two agricultural by-products, wheat bran and straw (w...

BACKGROUND Populations at low risk of colonic cancer consume large amounts of fibre and starch and pass acid, bulky stools. One short chain fatty acid (SCFA), butyrate, is the colon's main energy source and inhibits malignant transformation in vitro. AIM To test the hypothesis that altering colonic transit rate alters colonic pH and the SCFA content of the stools. PATIENTS Thirteen healthy ...

BACK GROUND For enzyme production, the costs of solid state fermentation (SSF) techniques were lower and the production higher than submerged cultures. A large number of fungal species was known to grow well on moist substrates, whereas many bacteria were unable to grow under this condition. Therefore, the aim of this study was to isolate a highly efficient strain of Bacillus sp utilizing wheat...

A preponderance of carcinogenesis studies in rodents and epidemiologic studies in humans suggests a potential role of dietary fiber in the prevention of colorectal cancer. Recently, wheat bran fiber used as a dietary supplement has been shown to decrease the growth of rectal adenomatous polyps in patients with familial polyposis; however, few studies of high-risk human populations have been att...

individual daily requirements recommend 25-35 g dietary fiber to maintain overall health and aid digestion. dietary fiber exists in fruits and vegetables, but can also be obtained by adding wheat bran to bread. wheat bran, however, contains high levels of phytic acid that is known to chelate iron, calcium, zinc, and magnesium and form complex phytic acid cations that reduce their bioavailabilit...

INTRODUCTION wheat bran has been known for many health benefits, but its glucose- and lipid-lowering activity still remains unresolved. OBJECTIVE to investigate effects of varying amounts of wheat bran and feeding period on serum glucose and lipids in sucrose-fed rats. METHODS eighty male Sprague-Dawley rats were assigned into 4 sucrose-based diets containing either 0, 5, 10 or 20% wheat br...

Fermentation of polysaccharides in the colon seems likely to regulate tumorigenesis but the mechanisms are unclear. A possible mechanism may be through facilitation of the acute apoptotic response to genotoxin-induced DNA damage. This study evaluated the effects of selected dietary polysaccharides, resistant starch (supplied as Hi-maize) and nonstarch polysaccharides (supplied as wheat bran and...

Grains of the wheat variety Tajan were milled into straight-run flour and bran. Proximate analysis, farinograph experiments and rheological characteristics were conducted. Two types of bran (hydrothermal treated and untreated) at three levels (0%, 5%, 10%) were added to the parent flour. Proximate analysis and farinograph experiments of these flours were conducted. The effects of adding treated...

effects of three nutritional levels of beet root molasses, cheese permeate, wheat bran extract, rice bran extract and sabouraud,s dextrose broth (sdb) were evaluated for blastospore production by two isolates of beauveria bassiana sensu lato. at an interval of 24 h for seven days. depending on the isolate, maximum blastospore production was obtained in 12% rice bran extract and 20% cheese perme...
