ABSTRACT
Sustainability in the energy consumption area is inextricably linked with the search of new alternatives. From the ecological point of view vegetable oil-based biofuels are in many aspects better than fossil fuels. The aim of the research is analysis of Jatropha curcas seeds in terms of weight ratio of the subcomponents, as a seed coat, seed kernel. Another aim is to determine the calorific value of these components and compare this value with the calorific value of pressed oil. It was determined that the kernel of Jatropha curcas is 62.7% and seed coat is 37.3%. The average unit weight of the seeds was 0.64 ± 0.11 g, of the seed kernel was 0.40 ± 0.09 and seed coat was 0.24 ± 0.03 g. In the light of statistic by Tukey HSD test there is not homogeneity between the tested calorific value and inconsumable residue series. The calorific value is of 36.7% lower in the case of energy utilization of the seed (i.e. seed kernel with seed coat) against to oil obtained by pressing.

    Jatropha curcas is considered a potential biodiesel feedstock crop. Currently, the value of J. curcas is limited because its seed yield is generally low. Transgenic modification is a promising approach to improve the seed yield of J. curcas. Although Agrobacterium-mediated genetic transformation...
