Banana’s pseudostem pulp (BPP) is a potential by-product obtained in the mechanical fiber extraction of banana’s pseudostem. Its chemical characterization revealed to have an interesting composition, with high polysaccharides content and low lignin, which makes it particularly relevant for biorefinery’s biochemical platform. Autohydrolysis pretreatment, studied under isothermal (140 °C) non-iso...

BACKGROUND There is considerable interest in the conversion of lignocellulosic biomass to liquid fuels to provide substitutes for fossil fuels. Pretreatments, conducted to reduce biomass recalcitrance, usually remove at least some of the hemicellulose and/or lignin in cell walls. The hypothesis that led to this research was that reactor type could have a profound effect on the properties of pre...

agricultural residues have high potential to produce biogas, but they contain lignocellulosicmaterials which are not easily degradable, so the pretreatment is required. chemical pretreatmentincreases the rate of degradation and efficiency of biogas production. this study has beeninvestigated the effect of 4% -urea, 5%-ammonia and 8%-sodium hydroxide on degradation of ricestraw and production of...

BACKGROUND Previous studies on the use of SO2 and CO2 as impregnating agent for sugar cane bagasse steam treatment showed comparative and promising results concerning the cellulose enzymatic hydrolysis and the low formation of the inhibitors furfural and hydroxymethylfurfural for the use of CO2 at 205°C/15 min or SO2 at 190°C/5 min. In the present study sugar cane bagasse materials pretreated a...

By discovering how chemical compounds/xenobiotics cytotoxicity is affected when their metabolic pathways are inhibited or activated, the metabolic pathways that activate versus detoxify chemical compound can be identified. Reactive metabolites contributing to cytotoxicity can also be identified. In this lecture, the pretreatment of inhibitors and activators of xenobiotic metabolizing enzymes as...

Medium-chain-length polyhydroxyalkanoates (mcl-PHAs), polyesters produced by bacterial fermentation of sugars and/or lipids, are potential bioplastic alternatives to petroleum-derived plastics. Lignocellulose is an abundant renewable source for fermentation. However, chemical or enzymatic release the requires a pretreatment step dispel rigid structure lignocellulose and enhance sugar access. Mo...

Abstract Volatile fatty acids (VFAs) are key platform chemicals used in a multitude of industries including chemicals, pharmaceuticals, food and agriculture. The current route for VFA production is petrochemical based. VFAs can be biologically produced using organic wastes as substrate, therefore directly contributing to sustainable economy. This process commonly known acidogenic fermentation (...

Common analytical challenges impact current work to estimate the cost of converting plant biomass to fermentable sugars. The most noteworthy are measuring cellulase and hemicellulase activities, cellulase and hemicellulase protein, biomass compositions (before and after pretreatment), and the products formed. The use of high-throughput (HTP) methods has shown considerable promise for improving ...

THE immunosuppressive agent FK 506 has been investigated for its adverse effects on the liver, kidney, and the pancreas. I FK 506, however, has multiple biological effects which may be beneficial for the liver. For instance, pretreatment of rats with FK 506 has been shown to both protect the liver from ischemic injury2 and to ameliorate the hepatic injury associated with ischemia and reperfusio...

Bioconversion of lignocellulose by microbial fermentation is typically preceded by an acidic thermochemical pretreatment step designed to facilitate enzymatic hydrolysis of cellulose. Substances formed during the pretreatment of the lignocellulosic feedstock inhibit enzymatic hydrolysis as well as microbial fermentation steps. This review focuses on inhibitors from lignocellulosic feedstocks an...
