Biotransformación y remoción de azufre a partir del dibenzotiofeno mediante métodos biocatalíticos mejorados
Resumen
Tres métodos de remoción de azufre a partir de dibenzotiofeno fueron evaluados empleando procesos biocatalíticos tales como byconversion microbiológica, enzimática y un método combinado que reúne la preoxidación via enzimática y la posterior degradación microbiana. La biodegradación fue evaluada sobre el modelo molecular dibenzotiofeno, encontrándose un mayor porcentaje de byconversion empleando el método combinado con respecto a los otros dos métodos. Los microorganismos evaluados corresponden a varias cepas colombianas aisladas por métodos directos de fuentes naturales y una cepa patrón como control positivo. Todas las cepas han presentado capacidad biodesulfurizadora y tolerancia a medios orgánicos. La enzima empleada corresponde a una hemoproteina con actividad peroxidasa, Citocromo C de corazón equino.
