For example, a novel method using a pulsed loop reactor has been developed for a more effective transesterification reaction of Jatropha crude oil (JCO) to J. curcas methyl …
J. curcas L., a potential bioenergy crop 70 million years old, is a monoecious, deciduous perennial small tree or shrub belonging to family Euphorbiaceae, to the tribe Jatropheae of the subfamily Crotonoideae. In 1737 Karl von Linne first described and in 1753 classified J. curcas.The genus name Jatropha comes from the Greek words …
El cultivo de plantas para la elaboracion de biocombustibles se viene desarrollando como una opcion para suplementar las necesidades energeticas de los paises de la region mesoamericana. Entre las diversas fuentes de materia prima oleaginosa para la produccion de biodiesel se encuentra Jatropha curcas L. Este arbusto oleaginoso recibe cada vez …
Jatropha curcas L. is a plant resistant to drought, versatile with many attributes and considerable potentials. The most valuable part of the plant is the oil content of the seed kernel. For optimum oil extraction, the seeds must be peeled almonds and separate the hulls. The separation of hulls almond is generally done manually which requires hard …
1. Introduction. Jatropha curcas L. has received a great deal of attention for its potential as a biofuel crop due to the high oil content of its seeds and because it can grow in soils with low nutrient content or water availability and on thin or steeply sloping soils [1, 2]. J. curcas seedlings are known to have consistent root system architecture, …
Background Jatropha curcas is an oil-bearing plant, and has seeds with high oil content (~ 40%). Several advantages, such as easy genetic transformation and short generation duration, have led to the emergence of J. curcas as a model for woody energy plants. With the development of high-throughput sequencing, the genome of …
Le Jatropha curcas peut produire jusqu'à 2 000 litres de diester par hectare (bien plus que le colza ou le soja). Toutefois, au début des années 1990, une tentative de culture au Nicaragua sur 2 000 hectares n'a pas tenu ses promesses et s'est révélée catastrophique, avec pour seul rendement 200 litres par hectare. En effet, bien que la plante soit en …
The toxicity, cytotoxicity and genotoxicity effects of J. curcas latex on the root cells of Allium cepa were examined and results showed that the mitotic index of the onion roots submitted to latex treatment decreased significantly compared to the negative control, which suggests that the latex is cytotoxic. The latex obtained from Jatropha curcas (physic nut) is used …
Un hectare de plantation de J. curcas de 1111 pieds (écartement 3 m x 3 m) âgée de 3 ans séquestre en moyenne 10787,81 kg C. Les résultats obtenus permettent de conclure que les plantations de J. curcas sont des puits de carbone et leur culture devrait prendre en compte le climat et le type de sol. Mots clés: Jatropha curcas ...

Resumen: En el presente trabajo se logró la obtención de biodiesel mediante una reacción de transesterificación entre el aceite extraído de Jatropha curcas L. y el metanol, con el empleo de hidróxido de potasio como catalizador. Además, como un subproducto del proceso se obtuvo glicerina. El biodiesel obtenido fue caracterizado …
The Jatropha genus is divided into two subgenera, Jatropha and curcas, from which the subgenus Jatropha has the widest distribution, with species found in Africa, India ...

Jatropha curcas seed meal was fermented with Bacillus licheniformis (LFJSM) and Bacillus pumilus (PFJSM) separately using the solid-state fermentation. After fermentation, the crude protein and the total hydrolysed amino acid contents were increased in LFJSM and PFJSM, while fibre content, phytic acid, trypsin inhibitor and saponins …
The production of biodiesel from Jatropha oil, is performed by Transesterification using ethanol in the presence of a catalyst such as NaOH. This project subject is to establish the optimum conditions to make ethanol transesterification from Jatropha oil curcas L. where the content of fatty acids and physico-chemical properties of oil are characterized.
The name Jatropha curcas was first used by Linnaeus, and although there are a number of synonyms this name is still valid today. J. curcas is in the spurge family, Euphorbiaceae, which is a pantropical family including 228 genera and over 6500 species of trees and shrubs (The Plant List, 2013).The genus Jatropha belongs to the tribe Jatropheae of the …
The residual recovery of J. curcas de-oiled cake and energy recoveries of the bio-crude were also presented. 2. Methods2.1. DESs preparation. De-oiled J. curcas cake was obtained after mechanical extraction of the seed, and sieved through 355 μm pore size sieve. All chemicals and reagents were analytical grade chemicals, except otherwise …
