“…The seeds make up approximately 70% of the total weight of the fruit and comprise of 41% shell and 59% kernel (Joshi et al, 2011b;Jongschaap et al, 2007). The kernel has up to 66.4% oil (Adebowale and Adedire, 2006) and moisture content of about 5% (Jongschaap et al, 2007).…”

“…The fatty acid composition of J. curcas oil showed that oleic acid (44.70 to 43.32%) is the most abundant followed by linoleic acid (36.70 to 32.80%) and palmitic acid (14.20 to 13.19%) (Abdullah et al, 2013;Akbar et al, 2009). J. curcas is not edible and the seed cake is not readily suitable for use as animal feed because it contains some toxicants like phorbol esters (Joshi et al, 2011b), curcins, phytates and protease inhibitors (He et al, 2011;Achten et al, 2008).…”

The industrial application of a vegetable oil is determined by the oil properties. This work was undertaken to alter the properties of Jatropha curcas Kernel oil and possibly find new applications for it. The seed kernels were roasted to different temperatures (140 to 230°C) and the physicochemical properties of the cold hexane and hot water extracted oils were studied. The oil yield, saponification, iodine, acid and peroxide values were affected by roasting temperature and method of extraction and these showed significant difference (p < 0.05). The calculated fuel properties: cetane number and calorific value were improved upon roasting, with cold hexane extracted oils yielding better results. Roasting improved the properties of the oil as diesel substitute but its suitability for use in paints and surface coatings formulation was reduced. The hot water extracted oil showed improved properties for soap production.

“…As an alternative, several researchers have focused on the biological detoxification by SSF as an efficient and cheap method to eliminate these undesirable compounds [35,[65][66][67][68][69][70][71]. Furthermore, if the waste is not useful after the treatment of detoxification, it may be thrown away in nature without producing soil or water contamination.…”

Abstract:The establishment of a bioeconomy era requires not only a change of production pattern, but also a deep modernization of the production processes through the implementation of novel methodologies in current industrial units, where waste materials and byproducts can be utilized as starting materials in the production of commodities such as biofuels and other high added value chemicals. The utilization of renewable raw resources and residues from the agro-industries, and their exploitation through various uses and applications through technologies, particularly solid-state fermentation (SSF), are the main focus of this review. The advocacy for biocatalysis in green chemistry and the environmental benefits of bioproduction are very clear, although this kind of industrial process is still an exception and not the rule. Potential and industrial products, such as biocatalysts, animal feed, fermentation medium, biofuels (biodiesel, lignocelulose ethanol, CH 4 , and H 2 ), pharmaceuticals and chemicals are dealt with in this paper. The focus is the utilization of renewable resources and the important role of enzymatic process to support a sustainable green chemical industry.

“…Thus, an ability to successfully cultivate each crop was the reason behind the different details of application of chemical fertilizer. Although the mixing of JSC at land preparation would aggravate the content of phorbol ester in the soil, such compound was hypothesized to decay at a harvest time (Joshi et al, 2011). Moreover, various rates of JSC would differently influence the growth and development of each crop.…”

The biodiesel from Jatropha curcas had been received much attention in these past decades. The seed was accountable for its high oil content. Through the development of oil expeller machine, the remains of an oil extraction were subjected to this study in order to examine the potential of deoiled Jatropha curcas seedcake (JSC) for being used as an organic fertilizer. However, the main concern was the presence of a toxic compound named phorbol ester in the JSC. The bio-safety questions were often regarded as the main concerns for the utilization of JSC as fertilizer. Therefore, the Chinese kale, tomato, and sweet potato were chosen to represent as the leaf, fruit, and tuber vegetable, respectively, which were subjected to the application of JSC as fertilizer. Here, the aspects of plant growth, yield, nutrient, and amount of phorbol ester in such plant parts as well as in the soil were analyzed. Although the treatments in each crops were practically the same, the specified details namely an exact rate of chemically fertilizer were slightly varied. The effects of half rate of chemical fertilizer mixed with high rate of JSC as fertilizer on the yields of Chinese kale and tomato were proven to be on the increase. This same treatment had mostly affected the growth characteristics of sweet potato. The total percentages of nitrogen (N), phosphorous (P), and potassium (K) in the vegetable products were subsequently inspected. Not only the qualities of pre-planting soil, in terms of pH, organic matter, and available P and K were analyzed, but also that of postharvest. Analytical measurements of phorbol ester via both HPLC and LC-MS/MS, were performed in all the samples from both harvested plant parts as well as soil. From all the postharvest propagations, the toxicity of phorbol ester could not be found, neither from the plant products nor the soil. Therefore, utilization of JCS as organic fertilizer for vegetable crops was marked as a safe practice, both for the consumer consumption and soil environment. This outcome can be of choice to solve the problem of rising fertilizer prices.
