Abstract

Procesos de fermentación para la producción de etanol incluyen suministrar un microorganismo termófilo que carece de actividad de lactato deshidrogenasa con azúcares en condiciones en las que los metabolicen de manera predominante mediante la ruta de piruvato formato liasa. De manera importante, los procesos también incluyen suministrar glicerol suficiente para convertir todos los azúcares en etanol. Una modalidad adicional de la invención incluye suministrar glicerol adicional suficiente para convertir el acetato exógeno presente en hidrolizados de biomasa en etanol. Es posible utilizar cualquier tipo de sistema de fermentación para estos procesos, pero una modalidad preferida incluye cultivos continuos a altas temepraturas, en lo que el etanol se retira de manera continua mediante evaporación al vacío.
