Biochemical conversion of wheat straw was investigated using hydrothermal pretreatment, enzymatic saccharification, and microbial fermentation. Pretreatment conditions that were compared included autocatalyzed pretreatment at 160, 175, 190, 205 °C sulfuric-acid-catalyzed 160 190 °C. The effects different with regard to (i) chemical composition digestibility pretreated solids, (ii) carbohydrate ...

Maize cobs can be used as a ruminant’s feed, but low digestibility and its quality improved by soaking in firewood ash filtrate (FAF). The study aimed to test FAF treatments' effect on rumen fermentation using completely randomized design. Firewood ashes were obtained from Sumedang, Indramayu, Bogor Regencies. maize soaked at ratio of 1:1 (w/v) for 3 hours different concentration, i.e. 0.05 w/v...

This study investigated the fermentability of hemicellulosic hydrolysates obtained by intensified steam explosion pretreatment switchgrass (Panicum virgatum) and Eucalyptus globulus. Xylitol carotenoids were high-value molecules produced fermentation. The allowed to process a large amount biomass per unit time resulted in containing high sugars, among which, significant fraction was form oligom...

Succinic acid is valued as a potential starting point for the production of chemicals of the C4 family or in the preparation of biodegradable polymers. For sustainable development in this era of petroleum shortage, production of succinic acid by microbial fermentation of renewable feedstock has attracted great interest. In this study, pretreatment with sulfuric acid and biotin supplementation w...

An experiment was conducted to study the effect of diets with contrasting fermentability in the large intestine on experimental infections with Brachyspira hyodysenteriae, the causative agent of swine dysentery, and the whip worm, Trichuris suis, in pigs. Two diets with organically grown ingredients were composed. Both diets were based on triticale and barley and supplemented with either rape s...

The present study aimed to evaluate the inter-individual variability in fermentation of standard fibrous substrates by faecal inocula from ten healthy adult female cats. Substrates were citrus pectin (CP), fructo-oligosaccharides (FOS), guar gum (GG), sugar beet pulp (SBP) and wheat middlings (WM). Each substrate was incubated with faecal inoculum from each cat. Gas production was measured cont...

An in vitro experiment was carried out to assess how nonstarch polysaccharide (NSP)-degrading enzymes influence the fermentation of dietary fiber in the pig large intestine. Seven wheat and barley products and cultivars with differing carbohydrate fractions were hydrolyzed using pepsin and pancreatin in the presence or not of NSP-degrading enzymes (xylanase and β-glucanase) and the filter reten...

Procedures for fermentative determination, in blood and urine, of glucose, or of sugars resembling it in their fermentability by yeast, have been refined by different investigators during the past few years. The chief source of error, undue prolongation of the time of fermentation to one or more days, was removed by Hiller, Linder, and Van Slyke (1925), who utilized conditions under which gluco...

In this work, the effect of particle size on the enzymatic hydrolysis of milled and sieved sugarcane bagasse (SCB) was studied. The enzymatic hydrolysis and fermentability of superfine ground SCB (SGP400) using an enzyme cocktail strategy were also explored. Particle size reduction improved the enzymatic hydrolysis. The highest glucose yield was 44.75%, which was obtained from SGP400. The enzym...

This study was designed to compare the effects of dietary supplementation with nondigestible carbohydrates, differing in fermentability by colonic bacteria, on hepatic steatosis in growing obese Zucker rats. Male Zucker fa/fa rats were divided into three groups: a control group that received the basal diet, a fructan group that received 10 g highly fermented Synergy 1/100 g diet and a cellulose...
