Applications

Algunas centrales termosolares utilizan el fluido calorportador Dowtherm A (HTF) para transferir el calor desde las parábolas hasta las turbinas que generan la electricidad. Este fluido está compuesto por una mezcla eutéctica de bifenilo (26,5%) y óxido de bifenilo (73,5%) y es un líquido altamente tóxico. El microorganismo de la invención degrada los dos componentes del HTF de tal forma que proporciona un método de biorremediación de suelos contaminados con HTF.
