Cost and limited reserves of conventional fossil fuels have intensified the search for alternative fuels for use in internal combustion engines. A possible alternative engine fuel is vegetable oil because it is a clean burning, renewable, non-toxic, biodegradable and environmentally friendly transportation fuel. It can be used in a neat form without any modification of the engine. Vegetable oil...

The ethalonic extract of the leaves of Jatropha tanjorensis Ellis & Saroja was tested for antimicrobial activities against gram positive - Bacillus cereus, Bacillus subtilis, staphylococcus aureus, gram negative E. coli and mycobacterium pheli.

for determining the oil content, seed and fruit characteristics of ethiopian jatropha provenances, the study was conducted in five regions of ethiopia namely southern nation nationalities peoples regional state, amhara region, tigria region, oromia region and benishangul gumuz regions, where jatropha is found abundantly. a total of 23 zones, 36 weredas and 40 sampling sites were considered from...

Geminiviruses are a group of plant viruses that contain circular single stranded (ss) DNA genomes encapsidated in small twinned icosahedral capsids .The virus DNA A plus strand encodes the coat protein (CP/AV1) essential for viral transmission by whiteflies (Bemisia tabaci)[4]. Jatropha has been found to have strong molluscicidal activity and the latex to be strongly inhibitory to watermelon mo...

In response to our article on the water footprint (WF) of bioenergy (1), Maes et al. (2) argue that we overestimated the WF of jatropha oil, used data from a limited number of plantations , and made methodological errors. We did use little data, because hardly any data on jatropha production are available. Although we took data from various plantations from different countries, Maes et al. stat...

Studies on organic seed fortification with Jatropha curcas and Pongamia pinnata using ‘Panchagavya ’at one, two, three, four and five per cent concentrations with the three different soaking durations revealed that Panchagavya at 2 and 5% with the soaking duration of 16 and 8 h were superior than the control and other concentrations in terms of germination and seedling vigour for Jatropha curca...

The direct feeding of Jatropha meal containing phorbol esters (PEs) indicated mild to severe toxicity symptoms in various organs of different animals. However, limited information is available on cellular and molecular mechanism of toxicity caused by PEs present in Jatropha meal. Thus, the present study was conducted to determine the cytotoxic and mode of action of PEs isolated from Jatropha me...

A study was carried out to assess carbon emission and carbon loss caused from land use change (LUC) of converting a wasteland into a Jatropha curcas plantation. The study was conducted for 12 months at a newly established Jatropha curcas plantation in Port Dickson, Malaysia. Assessments of soil carbon dioxide (CO(2)) flux, changes of soil total carbon and plant biomass loss and growth were made...

Propagation potentials of stem cuttings of different physiological ages and genotypes of physic nut (Jatropha curcas L.) were studied at UKM, Malaysia. Stem cuttings of the different physiological ages (hardwood, semi hardwood and soft wood) taken from five selected genotypes of Jatropha were planted in soil media (top soil). Data were collected on the attributes of the stem cuttings and then a...

BACKGROUND Jatropha curcas is an important biofuel crop due to the presence of high amount of oil in its seeds suitable for biodiesel production. Triacylglycerols (TAGs) are the most abundant form of storage oil in plants. Diacylglycerol O-acyltransferase (DGAT1) enzyme is responsible for the last and only committed step in seed TAG biosynthesis. Direct upregulation of TAG biosynthesis in seeds...
