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...

Genomic DNA was isolated from leaves of three species of Jatropha, namely J. glandulifera, J. gossypifolia and J. curcas. The objective of our study was to use alcohol as a fixing solution, making liquid nitrogen unnecessary for isolation of genomic DNA from Jatropha species. The spectral quality of genomic DNA isolated using this method as measured by the A260/A280 absorbance ratio ranged from...

The non-sulfided Ni-PTA/Al2O3 catalyst was developed to produce green diesel from the hydroprocessing of Jatropha oil. The Ni-PTA/Al2O3 catalyst was prepared by one-pot synthesis of Ni/Al2O3 with the co-precipitation method and then impregnanting Ni/Al2O3 with PTA solution. The catalysts were characterized with BET, SEM-EDX, TEM, XRD, XPS, TGA and NH3-TPD. The Ni and W species of the Ni-PTA/Al2...

Jatropha curcas has a variety of uses which are of great economic significance. Jatropha oil can be used as fuel alternative and for making biodiesel that is supposed to overcome the source limitation problem. In this study, conventional, ultrasound assisted and microwave pretreatment solid liquid extraction of Jatropha seed were studied in terms of amount and quality of the extracted oil. The ...

ISSN 2277-5056 | © 2013 Bonfring Abstract--Increasing the fuel demand brings us to find out the various alternative solutions. Out of the various research activities, bio-diesel from various oil seeds is the major activity, which decides the future energy sources. Our previous researchers concluded that Jatropha oil is to be an alternate fuel for Compression ignition (C.I) engines and it has cl...
