(FR) MILIEU DE FERMENTATION COMPRENANT DES EAUX USEES ET SON UTILISATION
Abstract
(EN)
The present invention relates to a fermentation medium comprising wastewater and a process for production of fermentation products such as lactic acid, combustible fuel product e.g. ethanol or cellbiomass by using wastewater derived from sewage such as municipal sewage, slaughterhouse waste, household waste or manure. The process comprises the steps of: (I) providing wastewater, (II) adding a biomass material to the wastewater of step (I) to obtain a biomass slurry, and (III) subjecting the slurry of step (II) to a fermentation process to obtain a fermentation product (IV) separating the fermentation product resulting from step (III).
(FR)
La présente invention se rapporte à un milieu de fermentation comprenant des eaux usées et à un procédé de production des produits de fermentation, notamment de l'acide lactique, à un produit de carburant, par exemple de l'éthanol ou une biomasse cellulaire au moyen d'eaux usées d'égouts, à savoir les égouts municipaux, les déchets d'abattoirs, les déchets domestiques ou le fumier. Le procédé consiste à : (i) fournir les eaux usées, (ii) ajouter une matière biomasse aux eaux usées de l'étape (i) afin d'obtenir une suspension de biomasse, et (iii) soumettre la suspension de l'étape (ii) à un procédé de fermentation afin d'obtenir un produit de fermentation, et (iv) séparer le produit de fermentation obtenu à l'étape (iii).
