Napier grass (Pennisetum purpureum), represents an interesting substrate for biogas production. The research project evaluated biogas potential production from dry anaerobic digestion of Napier grass using batch experiment. To enhance the biogas production from ensiled Napier grass, thermal and alkaline pre-treatments were performed in batch mode. Alkali hydrolysis of Napier grass was performed...

The composition of lipophilic extractives in the cortex and pith of elephant grass ( Pennisetum purpureum Schumach.) stems was thoroughly studied by gas chromatography-mass spectrometry. The predominant compounds were fatty acids followed by sterols (in free and conjugated forms as esters and glycosides). Other steroid compounds, as steroid hydrocarbons and ketones, were also present. Addition...

Because of a complex chemical ultra-structure of lignocellulosic biomass, pretreatment is a necessary step for its conversion into bio-ethanol. In the present study, pretreatment conditions using the ionic liquid (IL) 1-allyl-3methylimidazolium chloride ([Amim]Cl) were optimized for a relatively new model energy crop, hybrid Pennisetum (P. americanum × P. purpureum) to maximize the yield of fer...

COMPARATIVE studies of elephant and the F1 hybrids between ‘maiwa’ Cultivar millet (Pennisetum americanum) grass (P. purpureum) indicated a superiority in quality hybrids. To ascertain this potential animal performance was measured by exciting beef production on Pennisetum hybrid pastures consisting random mixture genotype which were grazed from July 28 to December 6. 1972 (132 days) 18 24 mont...

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...

This study aimed to the digestibility quality of Elephant Grass (Pennisetum purpureum) and concentrate with addition urea molasses in vitro. The was conducted vitro using an experimental method. design used a completely randomized (CRD) four treatments five repetitions: T0 (Elephant 100%), T1 60% + 40% Concentrate), T2 60%) % Umos 40%) T3 Concentrate 20% 20%). results showed no effect (P>0.0...

This experiment was conducted to determine the effect of cutting intervals on dry matter (DM) yield, yield components and nutrient contents four varieties Pennisetum purpureum. Varieties experimented include: Local green, purple, S13 S15. These were planted in a randomized complete block design with three replicates. All P. purpureum cut at 4, 8 12 weeks after cutback (WAC) represent first, sec...
