to evaluate the nutritive value in some lignocellulosic materials, 3 sets of experiments were conducted on aspen, and grape woods. to enhance the digestibility, the woods were treated with 5% naoh. throughout the first trial, chemical composition and digestibility coefficients of dry matter, organic matter and ndf of experimental feeds, ph of rumen, as well as palatability were evaluated while ...

The effects of polyethylene glycol (PEG) and polyvinylpyrrolidone (PVP) on in vitro gas production characteristics, organic matter digestibility (OMD), and metabolizable energy (ME) contents of some grape yield byproducts were investigated. The gas production was recorded after 2, 4, 6, 8, 12, 16, 24, 36, and 48 h of incubation. The gas production profiles in triplicate fitted with equation Y =...

A growing demand – above all in industrialised countries – for safer foods and cleaner production processes has been observed in recent times. This has led to a drive, by the agro-alimentary industries, for waste reduction and upgrading as a strategy to reduce costs and achieve new sources of income. In fact, waste may be a source of high-added value products potentially useful as beneficial fo...

Abstract Chloroethenes are widely used as solvent in the metal industry and dry cleaning industry, but their spillage into soil groundwater due to improper handling has negatively impacted human health. Bioremediation using microorganisms is one of technologies clean up contaminated with chloroethenes. In this study, we examined bioremediation chloroethene-contaminated wine pomace extract (WPE)...

Cabernet Sauvignon grape pomace contains carbohydrates and various amino acids that could be used as substrates for lactic acid (LA) production. In this study, a mutant strain of L. plantarum with deletion the D-lactate synthesis gene was developed to produce optical pure L-LA from pomace. The highest purity produced by 99.61%. direct bioconversion raw substrate showed low LA yield. Several pre...

Based on the structures of identified active ingredients, the phenolic compounds extracted from grape seeds and pine bark would not be expected to be genotoxic. Indeed, the inventor of pycnogenol states that this product was tested in Salmonella typhimurium and was negative. Substantial health claims for grape seed and pine bark extracts, including some studies showing tumor inhibition, make th...

In the last years, international guidelines encourage reduction of food waste or processing by-products to promote a circular economy approach. Winemaking represents one sectors with highest generation, several potential negative impact on environment. are mainly used produce distillates fertilizers, but interest in grape pomaceas source phenolic compounds has considerably increased. The aim th...
