Nowadays, the increasing demand for energy in the world is one of the main concerns for energy supply. In fact, the required energy can be obtained by increasing the production rate of fossil fuels such as oil and natural gas. However, improving the efficiency of the equipment and facilities might have a significant impact on production from hydrocarbon resources. With respect to this subject, ...

Abstract Studies on identifying numerous algae species to study the digestibility of rumen have yet be widely reported, especially with from tropical oceans. This experimentation was created assess gas production four Kelapa beach, Tuban, East Java, in vitro . The used a randomized block design treatments (four species: Laminaria sp., Padina australis, Eucheuma cottonii , and Gracilaria sp.) re...

BACKGROUND The bread-making process influences bread components, including phenolics that significantly contribute to its antioxidant properties. Five bread model systems made from different rye cultivars were investigated to compare their impact on concentration of ethanol-soluble (free and ester-bound) and insoluble phenolics. RESULTS Breads produced by a straight dough method without acid ...

Cassava pulp (CS) is high in fiber and low protein; hence, improving the nutritive value of CS required to increase its contribution enhancing ruminant production. The present work hypothesized that quality could be enhanced by fermentation with yeast waste (YW), which can used replace soybean meal (SBM), as well lead improved feed utilization ruminants. Thus, evaluation vitro ruminal digestibi...

Alternative functions, apart from cathepsins inhibition, are being discovered for stefin B. Here, we investigate its role in vesicular trafficking and autophagy. Astrocytes isolated from stefin B knock-out (KO) mice exhibited an increased level of protein aggregates scattered throughout the cytoplasm. Addition of stefin B monomers or small oligomers to the cell medium reverted this phenotype, a...

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 =...

in this research, chemical composition, gas production characteristics, effective degradability and nutritive value index (nvi) of dm and cp by in situ method of treated walnut hull by nurospora sitophila were studied. three fistulated kermani ram were used for determination of walnut hull degradability. data were analysed using completely randomize design. by processing walnut hull with neuros...

Thermal damage to proteins can reduce their nutritional value. The effects of toasting time on the kinetics of hydrolysis, the resulting molecular weight distribution of 00-rapeseed meal (RSM) and the soluble and insoluble protein fractions separated from the RSM were studied. Hydrolysis was performed with pancreatic proteases to represent in vitro protein digestibility. Increasing the toasting...

Acetic acid-soluble and insoluble proteins were isolated from doughs mixed in the presence of N-ethylmaleimide (NEMI). Reducedpyridylethylated acetic acid-insoluble protein (AF) and reducedpyridylethylated acetic acid-soluble protein (BF) were sequentially fractionated into an acetic acid-insoluble fraction (F-0), an acidic 70% ethanol-insoluble fraction (F-I), a neutral 70% ethanol-insoluble f...

Digestion of preparations of insoluble collagen of guinea fraction, “soluble collagen,” decreased with the age of the animal (2) have led to a considerable interest in the chemical basis of this “aging” phenomenon. The concept of the progressive formation, extracellularly, of covalent cross-links in collagen fibrils has recently received direct support from the reports of Bornstein, Kang, and P...
