Abstract
QUE COMPRENDE: a) COMBINAR, EN UN RECIPIENTE AGITADO Y AIREADO, UNA MUESTRA DE MINERAL CON UN CULTIVO BACTERIAL MATRIZ QUE INCLUYE 10% VOLUMEN/VOLUMEN DE UNA MUESTRA LECHOSA DE INOCULO MATRIZ A UN VOLUMEN DE SOLUCION NUTRIENTE; b) AUMENTAR EL VOLUMEN DE LA MUESTRA MINERAL Y EL INOCULO COMBINADOS A UN NIVEL DESEADO, UNA VEZ QUE LAS BACTERIAS DE LA SOLUCION COMBINADA ALCANZAN UN NIVEL DE 108 CELULAS/mL, TRANSFIRIENDO EL LIQUIDO A UN RECIPIENTE MAYOR CON LA ADICION DE AGUA O SOLUCION NUTRIENTE NECESARIA; Y, c) UTILIZAR EL AUMENTO DE VOLUMEN DE LAS BACTERIAS EN LA LIXIVIACION DE UNA MENA O CONCENTRADO. DICHA ADAPTACION PROCEDE A UNA TEMPERATURA ELEGIDA BASADA EN LA TEMPERATURA EXPERIMENTADA EN EL YACIMIENTO FUENTE DE DICHA MUESTRA. LA ADAPTACION INCLUYE ADEMAS INOCULAR EN FORMA CONTINUA UNA PILA PARA INUNDARLA CON LAS ESPECIES ADAPTADAS INTRODUCIDAS
