Acetate is normally regarded as an endproduct of anaerobic fermentation, but butyrate-producing bacteria found in the human colon can be net utilisers of acetate. The butyrate formed provides a fuel for epithelial cells of the large intestine and influences colonic health. [1-(13)C]Acetate was used to investigate the contribution of exogenous acetate to butyrate formation. Faecalibacterium prau...

In this study, the hydroxyl groups of cellulose acetate butyrate (CAB) oligomer were reacted with toluene diisocyanate-hydroxyethyl methacrylate (TDI-HEMA) adduct, in order to improve properties CAB such as flexibility, thermal stability etc. Then obtained modified was characterized by FTIR and 1H NMR analysis. UV-curable coating formulations prepared using oligomer, then applied on cotton fabr...

A biochemical model coupled with an iterative nonlinear least-squares program was used to estimate stoichiometric parameters for fermentat ion of soluble carbohydrate, starch, hemicellulose, cellulose and protein in the rumen. Fermentat ion parameters were deduced for two sets of l i terature data, on (1) a roughage group of 60 diets fed to 137 animals and (2) a concentrate group of 48 diets fe...

academic] Quercetin is a flavonol with potential health benefits including activities against cardiovascular disease, obesity, and oxidative stress. However, the benefits of quercetin are likely limited by poor bioavailability, primarily attributed to its poor aqueous solubility (due to its hydrophobicity and crystallinity) and extensive phase-II metabolism. Improving the apparent solubility of...

Butyrate is an important substrate for maintenance of colonic health and oligofructose fermentation by human faecal bacteria can increase butyrate production in vitro. However, oligofructose appears to be fermented by mainly acetate and lactate-producing bacteria rather than butyrate-producing bacteria. Isotope labelling studies using [U-(13)C(6)]glucose were used to show that (13)C(2) and (13)...

abstract— in the present study, genetic programming (gp) as a completely different approach in comparison with conventional methods, based on the imitation of natural evolution of living organism is proposed for the prediction of cellulose acetate (ca) polymeric membrane characteristics. the membrane preparation parameters of polymer concentration, additive concentration and coagulation bath te...

High surface lignin content (i.e. 34.6 %) sclerenchyma fiber bundles were successfully isolated with a yield of 71 % by mild alkali (NaOH dosage 5 wt%) extraction eucalyptus (Eucalyptus globulus) bark under 100 °C for 60 min.. The mechanical properties the composites prepared hot pressing cellulose acetate butyrate (CAB) sheets evaluated. exhibited good compatibility CAB due to their hydrophobi...
