“…Jatropha curcas offers a viable alternative in this context as it is not used for edible purposes, is grown only as a fencing plant and is well-adapted to varying soil conditions. Seeds of J. curcas accumulate about 35-40 % of oil (Achten et al 2008) in the form of triacylglycerol (TAG) and it varies according to the conditions of growth and agronomic practices (Openshaw 2000). In spite of its potential, the major bottleneck for the improvement of J. curcas for yield and seed quality traits is the narrow genetic diversity of the germplasm Sujatha 2007, 2009;Popluechai et al 2009;Wen et al 2010;Yi et al 2010).…”

Jatropha curcas has been widely studied at the molecular level due to its potential as an alternative source of fuel. Many of the reports till date on this plant have focussed mainly on genes contributing to the accumulation of oil in its seeds. A suppression subtractive hybridization strategy was employed to identify genes which are differentially expressed in the mid maturation stage of J. curcas seeds. Random expressed sequence tag sequencing of the cDNA subtraction library resulted in 385 contigs and 1,428 singletons, with 591 expressed sequence tags mapping for enzymes having catalytic roles in various metabolic pathways. Differences in transcript levels in early and mid-to-late maturation stages of seeds were also investigated using sequence information obtained from the cDNA subtraction library. Seven out of 12 transcripts having putative roles in central carbon metabolism were up regulated in early seed maturation stage while lipid metabolism related transcripts were detected at higher levels in the later stage of seed maturation. Interestingly, 4 of the transcripts revealed putative alternative splice variants that were specifically present or up regulated in the early or late maturation stage of the seeds. Transcript expression patterns from the current study using maturing seeds of J. curcas reveal a subtle balancing of oil accumulation and utilization, which may be influenced by their energy requirements.

“…It is important to point out that pure vegetable oils (VOs) can not be used directly in diesel engines because of the high viscosity, low volatility, and engine problems including coking on the injectors, carbon deposits, oil ring sticking, and thickening of the lubricating oils [4], [12].Yet, they can be used as base for liquid engine fuels in various ways, e.g. blends with other components, micro-emulsification, transesterification (TE), and hydrotreating [4].…”

Abstract-The interest in using Jatropha curcas L. (JCL) as a feedstock for the production of bio-diesel is rapidly growing. The properties of the crop and its oil have persuaded investors and policy makers consider JCL as a substitute for fossil fuels to reduce greenhouse gas emissions.In this paper, we give an overview of the currently available information on the different process steps of the production process of bio-diesel from JCL. Based on this collection of data and information the best available practice, the shortcomings and the potential environmental risks and benefits are discussed for each production step. The paper concludes with a call for general precaution and for science to be applied.

In the beginning, the diesel engine ran on vegetable oil, and it was peanut oil, an edible oil, that was first used for this purpose. As fossil fuels may become scarce and prices could escalate, soybean, canola/rapeseed, and other known oils are being used. As the discussion on food security, environmental protection, and energy generation continues, alternative sources of oils or fats for biodiesel synthesis are being studied. Waste frying oil and animal fats have also been used as feedstock for biodiesel production at the same time as nonedible oils ( Jatropha , castor), oil industrial plants coproduct (palm fatty acid distillate), and unconventional lipid sources (microbial oils and sewage sludge) have now been brought into light. When it comes to long‐term implementation of adoption in a commercial scale one of these so‐called nonconventional lipid sources, what has been observed is that continuous production of regular quality feedstock, adequate infrastructure for collecting or harvesting, storing, processing, and transporting (logistics) prevails; only cost‐effective choices have proven successful.
