Abstract
LA DESHALOGENACION ENZIMATICA DE COMPUESTOS ORGANOHALOGENADOS CON NITROGENO LIBRE SE LLEVA A CABO MEDIANTE LA ADICION DE DESHALOGENASA A UN COMPUESTO ACUOSO QUE COMPRENDA UN COMPUESTO ORGANOHALOGENADO CON NITROGENO LIBRE Y UN POLIMERO CATIONICO QUE CONTENGA NITROGENO. LA DESHALOGENACION ENZIMATICA DEL COMPUESTO ORGANOHALOGENADO CON NITROGENO LIBRE SE CONSIGUE SIN NINGUN EFECTO SUBSTANCIAL SOBRE EL COMPUESTO ORGANOHALOGENADO CON NITROGENO LIBRE. EL METODO DE DESHALOGENACION PUEDE LLEVARSE A CABO POR MEDIO DE PROCESOS CONTINUOS, POR TANDAS, O SEMICONTINUOS. EL COMPUESTO ES ESPECIALMENTE UTIL COMO FORMULA PARA FORTALECER UNA BANDA CONTINUA DE PAPEL, Y ES ADEMAS UTIL EN PROCESOS PARA LA FABRICACION COMERCIAL DE PAPEL. EL PRODUCTO DE PAPEL RESULTANTE COMPRENDE UN RESIDUO DE UN MICROORGANISMO. PREFERIBLEMENTE LA ENZIMA SE OBTIENE A PARTIR DE UN BIOCATALIZADOR, Y MAS PREFERIBLEMENTE A PARTIR DE UN MICROORGANISMO. EL ENRIQUECIMIENTO POR TANDAS DE UN CULTIVO DE UN MICROORGANISMO QUE CONTENGA DESHALOGENASA SUMINISTRA UN COMPUESTO CAPAZ DE ELIMINAR SUBSTANCIALMENTE LA PRESENCIA DE COMPUESTOS ORGANOHALOGENADOS CON NITROGENO LIBRE, LOS CUALES SON CONSIDERADOS COMO CONTAMINANTES. SE SUMINISTRAN CONCENTRACIONES DE CELULAS MAYORES DE 5 X 10 ELEVADO A 7 CELULAS / ML.
