The biodegradation of lignin, one of the most abundant carbon compounds on Earth, has important biotechnological applications in the derivation of useful products from lignocellulosic wastes. The purple photosynthetic bacterium Rhodopseudomonas palustris is able to grow photoheterotrophically under anaerobic conditions on a range of phenylpropeneoid lignin monomers, including coumarate, ferulat...

Ru/Al2O3 nano-catalysts were prepared with impregnation and microemulsion techniques. The supercritical water gasification reaction was performed at 400oC and 5-60 min. Within the tested operation conditions, the reaction residence time of 15 min was the optimum to maximize the H2 yield. It was observed that using microemulsion technique increases the total gas yield significantly. Using microe...

Performance responses to steam flaking flint corn as well as to the addition of roughage to finishing diets composed of whole flint corn were evaluated. Ninety-six Nellore bulls were stratified by initial BW (373 ± 11 kg) and randomly allotted to 16 feedlot pens (6 bulls/pen) in a randomized complete block design with 4 replicates/treatment. Dietary treatments for the 86-d feeding trial consist...

A combination of bagasse and waste oil, which is usually recovered in the industry from the effluent drains or at the machinery sections, is studied to generate a high CV fuel relative to the low CV bagasse fuel alone. The associated technical aspects such as excess steam generation, stack height requirements, economical returns due to the fuel mix are theoretically assessed in the present study.

A practicable, cost-effective and eco-friendly protocol of bagasse preservation for six months has been evolved. It envisages exposure of 4 ppm ozone once per month on 200 kg bagasse covered with polythene sheet. It afforded substantial (87%) reduction of bacterial, fungal and yeast count, concomitantly retaining initial properties of fiber, largely arresting degradation of cellulose and hemi-c...

in this research, the decay resistance of bagasse-polypropylene composite has been evaluated. the scope of research was to assess the effect of different weight percentages of bagasse (40, 55 and 70%) and coupling agent, (mapp) maleic anhydride grafted polypropylene (0, 4 and 6%) on the fungal decay of the composite. astm d1413-99 modified test method was used to carry out the decay test, trame...

The aim of our study was testing whether R. rosea extract and ferulic acid activate expression targets FoxO, regulators energy metabolism autophagy in livers young old mice, to what extent the effects on genes studied coincide. Methods. . C57BL/6J mice were reared at 22 ± 2 °С, 50-60% humidity, 12/12 hour light/dark cycle. All groups a standard chow (4,8% fats, 21,8% protein, 3,9% fibre). Exper...

From the root bark of Erythrina abyssinica a new pterocarpene [3-hydroxy-9-methoxy-10-(3,3-dimethylallyl)pterocarpene] and a new isoflav-3-ene [7,4'-dihydroxy-2',5'-dimethoxyisoflav-3-ene] were isolated. In addition, the known compounds erycristagallin, licoagrochalcone A, octacosyl ferulate and triacontyl 4-hydroxycinnamate were identified. The structures were determined on the basis of spectr...

Ferulate-mediated lignin/hemicellulose cross linking in grasses reduces in vitro NDF digestibility (IVNDFD). Impact of ferulate cross linking on animal performance was examined in lamb digestibility and dairy cow performance trials using the seedling ferulate ester (sfe) corn mutant that reduces cross linking and improves IVNDFD. Digestibility of control (W23) and 2 near-isogenic sfe (M04–4 and...
