In industrialized countries, it is expected that the future generation of bioenergy will be from direct combustion residues and wastes obtained biomass. Bioenergy production using woody biomass a fast developing application since this fuel source considered to carbon neutral. The harnessing these sources produces residue in form ash. As demand for increases, ash volumes increase. Major challenges arise relating efficient management byproducts. primary concerns are its storage, disposal, use...
Lignins are generally used as a low grade fuel in the pulp and paper industry. In this work, pyrolysis of Alcell Kraft lignins obtained from process Westvaco, respectively, was carried out fixed-bed reactor thermogravimetric analyzer (TGA) using helium (13.4 mL/min/g lignin) nitrogen (50 lignin), respectively. The reaction temperature increased 300 to 1073 K, while heating rates were varied 5 15 K/min. gaseous products mainly consisted H2, CO, CO2, CH4, C2+. With increase rate K/min both...
Biosurfactants are microbial products that have been increasingly researched due to their many identified advantages, such as low toxicity and high activity at extreme temperatures, but more importantly, they biodegradable compatible with the environment. versatile vast applications in clean-up of environmental pollutants through biodegradation bioremediation. They also food, pharmaceutical, other industries. These advantages wide range led continued interest biosurfactants. In particular,...
Sargassum fusiforme fucoidan (SFF) exhibits diverse biological activities. Insulin resistance (IR) implicated in type 2 diabetes (T2D) has become an epidemic health issue worldwide. In this study, we investigated whether SFF can improve insulin sensitivity high-fat diet (HFD)-fed mice. Our present data showed that significantly reduced fasting blood glucose and IR index along with improved tolerance. Impaired phosphorylation of Akt was also restored by SFF. Furthermore, decreased the levels...
Insulin resistance is a characteristic feature of type 2 diabetes. Sulforaphane (SFN) natural antioxidant extracted from the cruciferous vegetables. Recent study reported that SFN exhibits excellent anti-diabetic effects, however, underlying mechanism still unclear. This aimed to investigate therapeutic effects on high-fat diet (HFD)-induced insulin and potential mechanism. was found effectively reduce body weight, fasting blood glucose hyperlipidemia, improve liver function in HFD-fed mice....
In this study, three advanced oxidation processes (AOP) were investigated for their capabilities to reduce petroleum hydrocarbons (PHC) in oily sludge. These include ultrasonic treatment alone, Fenton's reaction process and the combination of ultrasound (US/Fenton). Under experimental conditions, achieved a reduction 22.6% 13.8% total (TPH), respectively. However, TPH 43.1% was observed combined reaction, indicating that individual AOP is complementary one another. As result, could be acted...
Metformin is widely used to surmount insulin resistance (IR) and type 2 diabetes. Accumulating evidence suggests that metformin may improve IR through regulating gut microbiota bile acids. However, the underlying mechanisms remain unclear. Our metabolomic analysis showed significantly increased accumulation of tauroursodeoxycholic acid (TUDCA) in intestine liver from high-fat diet (HFD)-induced mice. TUDCA also alleviated IR, reduced oxidative stress intestinal inflammation ob/ob blocked...
ABSTRACT A prototype solvolytic lignin has been fractionated into three fractions by successive extraction with organic solvents of increasing hydrogen-bonding capacity. comparison between the and starting made in terms methoxyl group content, fractionation yields, molecular weight distribution, alkaline nitrobenzene oxidation, 1H and13 C NMR spectroscopy. The procedure was found to isolate having distinct functionalities distributions. In particular, heterogeneity ALCELL® is demonstrated...
