For determining the fatty acid characteristics and biodiesel quality of Ethiopian Jatropha provenances, the study was conducted in five regions namely Southern Nation Nationalities Peoples Regional State (SNNPRS), Amhara region, Tigria region, Oromia region and Benishangul Gumuz Regions, where physic nut is found abundantly. For each region, representative sampling sites were selected following...

BACKGROUND Jatropha curcas L. (Jatropha) is believed to have originated from Mexico and Central America. So far, characterization efforts have focused on Asia, Africa and Mexico. Non-toxic, low phorbol ester (PE) varieties have been found only in Mexico. Differences in PE content in seeds and its structural components, crude oil and cake from Jatropha provenances cultivated in Central and South...

Jatropha curcas leaves extract was tested as a green corrosion inhibitor for mild steel in aqueous hydrochloric acid solution using gravimetric and thermometric techniques. The results reveal that the inhibition efficiency vary with concentration of the leaf extract and the time of immersion. Maximum inhibition efficiency was found to be 95.92% in 2M HCl with 0.5 g/l concentration of the extrac...

Jatropha curcas is a promising renewable feedstock for biodiesel and bio-jet fuel production. To study gene expression in Jatropha in different tissues throughout development and under stress conditions, we examined a total of 11 typical candidate reference genes using real-time quantitative polymerase chain reaction (RT-qPCR) analysis, which is widely used for validating transcript levels in g...

molecular characterization of 19 jatropha accessions that included 15 accessions of j.curcas and 4 different species was carried out using 3 different markers systems. highest polymorphism (96.67%) was recorded by rapd followed by damd (91.02%) and issr (90%). polymorphism information content (pic) was higher for damd (0.873) and almost equal for rapd (0.863) and issr (0.862) markers, whereas r...

The simultaneous esterification and transesterification of Jatropha curcas oil (JCO) was carried out in the presence of Bi2O3 (1–7 wt.%) modified La2O3 catalyst at atmospheric pressure. The catalyst were characterized by X-ray diffraction (XRD), BET surface area, desorption of CO2 (TPD-CO2) and NH3 (TPD-NH3). Under the optimal reaction condition of methanol/oil molar ratio of 15:1, 2 wt.% of ca...

As a measure of testing the medicinal properties of Jatropha curcas, methanol extract obtained from both in vivo leaf and leaf derived callus were subjected to antimicrobial activity against six microorganisms, of the six different concentrations tested, the in vitro leaf callus extracts of at high concentrations (1.0 and 1.2%) inhibited the growth of Staphylococcus aureus and Pseudomonas sp. a...
