Our previous study indicated that formation of furanocoumarin phytoalexins could be induced in Glehnia littoralis root cultures by treatment with 10-40 mM ascorbic acid (AsA). This furanocoumarin production is much less evident when G. littoralis roots are treated with AsA under iron-deficient conditions. Instead, two large unknown peaks appeared in the HPLC chromatogram, whose chemical structu...

New clerodane diterpenes, 12-epi-megalocarpodolide D (2) and an epimeric mixture of crotonolins A (3) and B (4), were isolated from the bark of Croton oligandrus following a bioassay-guided isolation protocol. Known compounds, megalocarpodolide D (1), 12-epi-crotocorylifuran (5), cluytyl-ferulate (6), hexacosanoyl- ferulate (7), vanillin (8), acetyl-aleuritolic acid (9) and lupeol (10), were al...

The structure of the lignin in the cortex and pith of elephant grass (Pennisetum purpureum) stems was studied both in situ and in isolated milled "wood" lignins by several analytical methods. The presence of p-coumarate and ferulate in the cortex and pith, as well as in their isolated lignins, was revealed by pyrolysis in the presence of tetramethylammonium hydroxide, and by 2D NMR, and indicat...

Cashew bagasse consists of a residual food-processing material, rich in polyphenols. The aim of the present study was to investigate the kinetic of phenolics compounds recovery from cashew bagasse by hydroethanolic extraction. Process was carried out at 0, 20, 40, 60, 80, 100 and 120 minutes in a shaker at 50 °C and 90 min -1 . An ethanol aqueous mixture (50 %, w/w) was chosen as solvent and a ...

Wood shortages, environmental pollution and high energy consumption remain major obstacles hindering the development of today's pulp and paper industry. Energy-saving and environmental friendly pulping processes are still needed, especially for non-woody materials. In this study, soda-oxygen pulping of bagasse was investigated and a successful soda-oxygen pulping process for bagasse at 100 °C w...

Sugarcane bagasse and trash may be used as feedstock for second generation ethanol production. Production of second generation ethanol integrated with first generation plants processing sugarcane presents several advantages over the stand-alone second generation ethanol production process; however, bagasse is used as fuel to supply the energy demand of the first generation process, so the amoun...

Bagasse flour (BF) was liquefied using bi-component polyhydric alcohol (PA) as a solvent and phosphoric acid as a catalyst in a microwave reactor. The effect of BF to solvent ratio and reaction temperatures on the liquefaction extent and characteristics of liquefied products were evaluated. The results revealed that almost 75% of the raw bagasse was converted into liquid products within 9 min a...

Sugarcane bagasse is an abundant and sustainable resource, generated as a by-product of sugarcane milling. The cellulosic material within bagasse can be broken down into glucose molecules and fermented to produce ethanol, making it a promising feedstock for biofuel production. Mild acid pretreatment hydrolyses the hemicellulosic component of biomass, thus allowing enzymes greater access to the ...

Semi-solid state fermentation route of hydrogen production from agrowaste sugarcane bagasse was tried using the photosynthetic bacterium Rhodopseudomonas (BHU strain-1) and the non-photosynthetic Enterobacter aerogenes MTCC2822. The process seems an alternative to submerged fermentation that requires high volumes of nutrient broth. Bagasse (10 g) pre-hydrolyzed with NaOH (2%, w/v) was coated wi...

A biocomposite is a material formed by a matrix and a reinforcement of natural fibers like Jute, Coir, Sisal, Pineapple, Ramie, Bamboo, Banana and Bagasse, etc. Such natural fibers composites are low-cost fibers with high specific properties, low density and eco-friendly. The development of advanced biocomposite materials made is increasing worldwide. It will be an alternative way to develop th...
