Abstract

SE REFIERE A UNA CEPA BACTERIANA AISLADA DE LA ESPECIE ACIDITHIOBACILLUS THIOOXIDANS DENOMINADA LICANANTAY, DEPOSITADA COMO DSM 17318 Y QUE UTILIZA COMPUESTOS DE AZUFRE REDUCIDO PARA SOSTENER EL CRECIMIENTO AUTOTROFICO. DICHA CEPA PRESENTA UNA ACTIVIDAD AUMENTADA EN LA LIXIVIACION DEL COBRE DE MENAS SULFURADAS MIXTAS, EN ESPECIAL LAS QUE CONTIENEN CALCOPIRITA, BORNITA, CALCOSINA, COVELINA, ENTRE OTRAS ESPECIES MINERALOGICAS DE COBRE. SE REFIERE TAMBIEN A UN PROCESO DE BIOLIXIVIACION DE MINERALES QUE CONSISTE EN LIXIVIAR LA MENA SULFURADA CON SOLUCIONES ACIDAS BACTERIANAS QUE CONTIENEN LA CEPA LICANANTAY DSM 17318 PARA LA OBTENCION DE COBRE, A UNA TEMPERATURA MENOR DE 35 ºC Y UN pH DE 1,0 A 2,5
