“…Extraction of protein from defatted seed cake has been described as a way of reducing the contents of antinutrient and toxic components (Marrufo-Estrada et al, 2013) with high levels of protein, which often have digestibility similar or greater than that of fishmeal protein (Makkar et al, 2008). Since rubber kernel meal contain less protein, a large amount of indigestible material and anti-nutrients, there is need to convert them into a better useful products by isolating the protein for optimum utilization.…”

a b s t r a c tThe nutritional potential of protein isolate from rubber seed (RPI) in the diets of Labeo rohita (initial average weight 4.45 ± 0.01 g) was assessed in a 60 days feeding trial. Five isonitrogenous (32.62 ± 0.13 CP Kg −1 ) and isocaloric (18.47 ± 0.08 MJ kg −1 ) experimental diets were formulated with graded level of RPI like 0%, 25%, 50%, 75%, or 100% in replacement for soybean protein isolate (SPI), and designated as Control, RPI25, RPI50, RPI75, RPI100, respectively. The RPI contributed 0%, 13%, 26%, 39% or 52% of the total dietary protein in the diets. Each diets were randomly assigned to 15 experimental tanks containing 12 fish in triplicates and fed to satiation twice daily at 10:00 h and 18:00 h. At the end of the feeding trial, the growth performance and nutrient utilization indices such as percent weight gain (WG%), specific growth rate (SGR), daily growth coefficient (DGC), feed intake (FI), protein efficiency ratio (PER), feed conversion ratio (FCR) and protein retention (PR) values were not significantly (p > 0.05) affected by the dietary treatments irrespective of inclusion levels of RPI. A significantly higher (p < 0.05) hepatosomatic index (HSI) was recorded in the control and RPI 50 group compared to other treatment groups (p < 0.05). The intestinal somatic index (ISI) and Survival rate were similar (p > 0.05) in all the groups. The apparent digestibility coefficients (ADCs) of dry matter and protein for fish fed the control and RPI 100 diets were found to be similar, while RPI 50 and RPI 75 groups exhibited a significantly lower value corresponding to the protease enzyme activity. The whole body compositions and digestive/metabolic enzymes activities among the various groups did not differ significantly (p > 0.05). The serum cholesterol and triglyceride levels were found to be significantly higher (p < 0.05) in the control compared to the RPI fed groups. Significantly higher serum glucose level was recorded in RPI 50, while a reverse was seen in the liver glycogen contents. Overall, this study clearly showed that RPI from rubber seed can serve as alternative protein source in the diets of L. rohita fingerlings without any adverse effects on growth, nutrient utilization and physio-metabolic responses.

“…Com base nos valores de composição química encontrados para FDN (62,67 ± 3,13%), FDA (51,9 ± 2,10%), celulose (33,29 ± 1,13%) e proteína bruta (32,92 ± 0,78%), é possível conjecturar que a torta de pinhão-manso, subproduto das indústrias de biodiesel e óleos vegetais, tem potencial como matéria-prima para agroindústrias de produção de ração animal, fertilizantes orgânicos e etanol de segunda geração (MAKKAR et al, 2008;DEVAPPA;SWAMYLINGAPPA et al, 2008;KING et al, 2009;BECKER, 2009). Entretanto, devido à presença de toxinas e fatores antinutricionais ésteres de forbol, fitalatos, lectinas, inibidores de tripsina, saponinas, glicosídeos cianogênicos (MARTÍNEZ-HERRERA et al, 2006), na torta pinhão-manso, o uso dessa biomassa como ração animal é limitado, sendo necessária a utilização de tratamentos destoxificantes (KING et al, 2009).…”

ResumoA torta de pinhão-manso (Jatropha curcas L.), coproduto do processo de obtenção do biodiesel, apresenta um percentual significativo de carboidratos poliméricos em sua composição. Uma estratégia atraente para o aproveitamento dessa biomassa seria a biotransformação de seus carboidratos para a produção de etanol. Nesse contexto, o presente estudo teve por objetivo avaliar a composição da torta de pinhão-manso, bem como promover a otimização do processo de sacarificação enzimática da fração amilácea contida na torta e avaliar, também, a fermentabilidade do hidrolizado enzimático para produção de bioetanol. O planejamento experimental utilizado seguiu um modelo Composto Central Rotacional (CCR), cujos fatores avaliados foram o tempo de hidrólise e a concentração de enzima amilolítica, resultando em rendimento hidrolítico de 90%. O processo fermentativo realizado com Saccharomyces cerevisiae e o hidrolisado amiláceo derivado da torta de pinhão-manso apresentou valores de eficiência fermentativa de 100%. O uso da torta de pinhão-manso para produção de bioetanol pode ser uma estratégia eficiente se associada à cadeia produtiva do biodiesel como forma de agregar valor a um coproduto abundante e como alternativa para produção de uma fonte de energia renovável.Palavras-chave: biomassa; etanol; fermentação; hidrólise; Jatropha curcas L.

“…J. curcas can provide opportunities for additional income and therefore improve food security (Lyimo, 2010). To enhance the value of JKC, several methods have been proposed for its detoxification, such as: (1) solvent extraction methods (Chivandi et al, 2004;Martınez-Herrera et al, 2006;Makkar et al 2008;Rachadaporn et al, 2012); (2) chemical treatment methods Haas and Mittelbach, 2000;Aregheore et al, 2003;Devappa and Swamylingappa, 2008;Azza and Ferial, 2010); (3) biodetoxification methods such as fungal detoxification (Belewu and Akande, 2010;Azhar et al, 2014Sulaiman et al, 2014), bacterial detoxification (El-Zelaky et al, 2011;Phengnuam and Suntornsuk, 2013;Widiyastuti et al, 2013;Chin-Feng et al, 2014) and ensilage (Oliveira et al, 2012); physical methods such as ionizing radiation (Runumi et al, 2014), ozonation and solar irradiation (Susan et al, 2015), heat (Workagegn et al, 2013), roasting (Azza and Ferial, 2010), germination (Azza and Ferial, 2010), soaking (Azza and Ferial, 2010), and boiling (Annongu et al, 2010;Fakunle et al, 2013;Alatise et al, 2014).

Jatropha curcas Linnaeus, 1753 is a plant with several uses for communities in Cameroon and other African countries. However, present methods of detoxifying J. curcas kernel cake (JKC) to add value to its further utilization are too sophisticated for cottage operations in rural areas. This study sought to evaluate two auto-detoxification methods using the shellfish brine shrimp, Artemia salina (Linnaeus, 1758). Two identical J. curcas auto-detoxification apparatuses (JADA) were developed: one simulating diffuse daylight (DJADA) and the other solar irradiation (SJADA) conditions. JKC was pretreated by either soaking or boiling in water or lye. The pretreated samples were then placed in the JADA and either re-moistened to 66% dry matter (DM) or left un-moistened. Among the 14 pretreated samples, water soaked solar without re-moistening (WS1), lye soaked solar without re-moistening (LS1), and water soaked solar with re-moistening (WS2) had LC 50 values above 1000 ppm after four weeks. On the other hand, un-moistened diffuse daylight spread (UDC), boiled in water and exposed to diffused daylight without remoistening (WD3), and un-moistened solar spread (USS) were the least detoxified within the same period of four weeks with LC 50 values less than 60 ppm. Irrespective of the pretreatment, extracts from the SJADA had higher LC 50 values when compared to that of DJADA. This finding suggests that sunlight is an important factor in auto-detoxification. The top three most efficient detoxified treatments: WS1, LS1 and WS2 are recommended for further development and testing with livestock and fish models. This study confirms that JKC is toxic, but under natural conditions is exposed to auto-detoxifying factors which are both endogenous and environmental. When these conditions are optimally manipulated, the detoxification rate is enhanced. Farmers in rural communities can use this strategy to detoxify JKC, transform it into livestock and fish dietary ingredient and consequently enhance its contribution to climate change mitigation.
