Modelado de la biodegradación en biorreactores de lodos de hidrocarburos totales del petróleo intemperizados en suelos y sedimentos (Biodegradation modeling of sludge bioreactors of total petroleum hydrocarbons weathering in soil and sediments)
Because of its fatty acid profile (FAP) Jatropha curcas seed oil is considered suitable to produce biodiesel. FAP indicates the presence and proportion of different fatty acids such as oleic acid, linoleic acid, palmitic acid, and stearic acid. However, the FAP is variable between populations of the same species, therefore the quality of the biodiesel produced varies from one accession to another. Different genetic improvement programs select and cross plants to improve seed yield, nonetheless, it is necessary to obtain new varieties with the appropriate FAP for high-quality biodiesel production. In the present work, the variability of the FAP of 24 accessions (6 parents and 3 controls and 15 F1 hybrids) was evaluated, as well as the use of fatty acids as chemical descriptors. The FAP was determined by GC-MS chromatography, their variability and interdependence were evaluated to establish the fatty acids (or the relationship among them) that could be used as trait. Finally, a method is proposed to assign trait states considering the variability of the character value, for use as a varietal chemical descriptor.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
