To study oil contents and fatty acid composition among the samples of Jatropha curcas L. seeds were collected from Dehradun, Uttarakhand. Soxhlet extraction method and gas chromatography (GC) were employed to determine the oil contents of Jatropha seeds and the fatty acid composition of Jatropha oil. The seed oil contents (dry basis) was 46.27% .Physicochemical properties shows acid value (36.4...

Correction We found an important error in our published paper [1]. On page 7, Section: One-step conversion of Jatropha oil to biodiesel, line 3, we wrote a reaction temperature of 120degreesC. The correct temperature should be 220degreesC. The pressure was also omitted from the same reaction description and should be 7.1 MPa. Direct production of biodiesel from high-acid value Jatropha oil with...

91 10.4155/BFS.09.4 © 2010 Future Science Ltd Jatropha curcas L. (further referred to as Jatropha) is a rapidly emerging biofuel crop currently attracting a lot of interest and investments [1]. This stem-succulent [2] deciduous tree or shrub produces seeds rich in toxic oil (27–40% [3]). The oil can be extracted easily with techniques of different sophistication levels [4,5]. The crude Jatropha...

Erva cidreira (Melissa officinalis) is a plant with sedative properties and in Brazil it has been used for insomnia and anxiety. It is also employed to stimulate liver functions and normalize menstruation and for intestinal constipation. The aim of this work was to evaluate the genotoxic and mutagenic effects of erva cidreira. Results indicate the presence of genotoxic activity in the lyophiliz...

103103-0707 IJMME-IJENS © June 2010 IJENS I J E N S Abstract— The world is getting modernized and industrialized day by day. As a result vehicles and engines are increasing. But energy sources used in these engines are limited and decreasing gradually. This situation leads to seek an alternative fuel for diesel engine. Biodiesel is an alternative fuel for diesel engine. The esters of vegetables...

Biodiesel is emerging as a promising substitute of an alternative fuel and has gained significant attention due to the predicted depletion of conventional fuels availability in near future and environmental pollution concern. Utilization of biodiesel produced from Jatropha oil by transesterification process is one of the most promising options to replace conventional fossil diesel fuel. The phy...

Out of various no edible oil resources, jatropha curcas oil is considered as a promising alternate fuel for CI engines. The present study describes the process used for production of degummed jatropha oil (DGJO) and jatropha methyl ester (JBD) The important fuel properties of DGJO and JBD were determined and compared with fossil diesel and jatropha oil. The degumming and trans esterification pr...

Poly(3-hydroxybutyrate) (PHB) is a biodegradable polymer that can be synthesized through bacterial fermentation. In this study, Cupriavidus necator H16 is used to synthesize PHB by using Jatropha oil as its sole carbon source. Different variables mainly jatropha oil and urea concentrations, and agitation rate were investigated to determine the optimum condition for microbial fermentation in bat...

The genus Jatropha is distributed through out the tropics and sub-tropics growning in marginal lands and is a potential biodiesel crop world wide. The plants can prevent soil erosion, grown as a live fence and used as an alternate commercial crop. The seed oil can be used as a feed stock for biodiesel. Alternatively Jatropha oil is used in soap, glue or dye industry. The seed cake is rich in ni...
