Mapping of QTLs for Seed Phorbol Esters, a Toxic Chemical in Jatropha curcas (L.)
Jatropha (Jatropha curcas L.) is an oil-bearing plant that has potential to be cultivated as a biodiesel crop. The seed cake after oil extraction has 40-50% protein that can be used in animal feeds. A major limitation in utilizing the cake is the presence of phorbol esters (PE), a heat-tolerant toxic chemical. To identify the quantitative trait loci (QTLs) for PE, we constructed a genetic linka...
متن کاملBio-detoxification of Jatropha curcas seed cake by Pleurotus ostreatus
The detoxification of Jatropha curcas seed cake is of major interest for the biodiesel industry to add economic value to this residue and also to reduce the environmental damage caused by its inappropriate disposal. In this context, the treatment of this residue with white rot fungus, Pleurotus ostreatus, can be a viable alternative because it produces enzymes capable of degrading different lig...
متن کاملPhorbol Esters Degradation and Enzyme Production by Bacillus using Jatropha Seed Cake as Substrate
The purposes of this research were to evaluate phorbol esters (PEs) degradation rate and enzyme production yield using submerged fermentation (SMF) as screening method and further using solid-state fermentation (SSF) as pilot scale-up study. SMF was carried out with 20 g seed cake in 100 ml minimal salt medium for 7 days incubation, while SSF was done with 20 g seed cake at 50% moisture content...
متن کاملPhorbol esters seed content and distribution in Latin American provenances of Jatropha curcas L.: potential for biopesticide, food and feed
BACKGROUND Jatropha curcas L. (Jatropha) is believed to have originated from Mexico and Central America. So far, characterization efforts have focused on Asia, Africa and Mexico. Non-toxic, low phorbol ester (PE) varieties have been found only in Mexico. Differences in PE content in seeds and its structural components, crude oil and cake from Jatropha provenances cultivated in Central and South...
متن کاملDetoxification of Toxic Phorbol Esters from Malaysian Jatropha curcas Linn. Kernel by Trichoderma spp. and Endophytic Fungi
The presence of phorbol esters (PEs) with toxic properties limits the use of Jatropha curcas kernel in the animal feed industry. Therefore, suitable methods to detoxify PEs have to be developed to render the material safe as a feed ingredient. In the present study, the biological treatment of the extracted PEs-rich fraction with non-pathogenic fungi (Trichoderma harzianum JQ350879.1, T. harzian...
