Abstract

QUE COMPRENDE: a) ESTABLECER UN ENTORNO BAJO CONDICIONES CONTROLADAS, EN DONDE SE USA MICROORGANISMOS MESOFILOS, TERMOFILOS MODERADOS O TERMOFILOS, PARA OXIDAR UNA SUSPENSION CONTENIENDO MINERALES SULFURADOS DE METALES COMO PIRITA, PENTLANDITA, ENARGITA, CALCOPIRITA, CINABAR, COVELITA Y BORNITA; b) SUMINISTRAR UNA ALIMENTACION DE GAS CONTENIENDO MAS DE 21%; c) AGREGAR AL ENTORNO UNO O MAS METALES DISUELTOS, PEQUENAS CANTIDADES DE COMPUESTOS ORGANICOS Y UNO O MAS NUTRIENTES INORGANICOS COMO N,P Y K; d) APLICAR UNA PRESION MUTAGENICA ESPECIFICA A LOS MICROORGANISMOS; e) CONTROLAR LA CONCENTRACION DE SOLIDOS MINERALES EN LA SUSPENSION; f) CONTROLAR EL TIEMPO DE RETENCION HIDRAULICO DEL REACTOR; g) MANTENER LA CONCENTRACION DE OXIGENO DISUELTO EN LA SUSPENSION, ENTRE 0,0002 Kg/m3 Y 0,01 Kg/m3; Y, h) SEPARAR Y RECUPERAR LOS BIOPRODUCTOS DESDE LA SUSPENSION. EL ENTORNO SE ESTABLECE EN UNO O MAS RECIPIENTES REACTORES QUE INCLUYEN UN IMPULSOR PARA AGITAR LA SUSPENSION. LOS BIOPRODUCTOS RECUPERADOS SON MICROORGANISMOS O SUS METABOLITOS. LOS MICROORGANISMOS DE (a) SE OBTIENEN DE FUENTES DE MUESTRAS LIQUIDAS O SOLIDAS DE VERTEDEROS DE CARBON, AREAS TERMALES VOLCANICAS Y MANANTIALES TERMALES DEL INTERIOR, TODAS CONTENIENDO AZUFRE. LA TEMPERATURA DE OPERACION ES ENTRE 60°C Y 85°C
