Abstract

Los sistemas convencionales de fermentación adolecen de tres problemas básicamente: Bajas eficiencias o productividad de la fermentación, bajas concentraciones del etanol producido que aumentan los costos de su separación y purificación y altos flujos de agua contaminada o vinazas. La presente invención se basa en la integración de un sistema de membrana a un sistema de fermentación sin sangrado del fermentador en un proceso que puede funcionar en continuo o semi-continuo. Esta membrana tiene la capacidad de remover etanol y todos los otros componentes de inhibición que se generen mientras al mismo tiempo se puede usar una segunda membrana para retener y/o remover biomasa de acuerdo a las características de los microorganismos utilizados. En la operación en continuo el fermentador puede ser alimentado con altas concentraciones de sustrato.Conventional fermentation systems basically suffer from three problems: Low efficiencies or productivity of fermentation, low concentrations of ethanol produced that increase the costs of its separation and purification, and high flows of contaminated water or stillage. The present invention is based on the integration of a membrane system to a fermentation system without bleeding from the fermenter in a process that can operate continuously or semi-continuously. This membrane has the ability to remove ethanol and all the other inhibiting components that are generated while at the same time a second membrane can be used to retain and / or remove biomass according to the characteristics of the microorganisms used. In continuous operation the fermenter can be fed with high concentrations of substrate.
