Production of hydrogen and ethanol with aeration pretreated sludge and glycerol as substrate

Abstract

Las recientes investigaciones se han enfocado en la búsqueda de nuevas fuentes de energías renovables, así el biohidrógeno y bioetanol son fuentes de energía renovable que podrían responder a la problemática energética, ambos pueden ser producidos en conjunto a través de la fermentación oscura, utilizando como materias primas residuos industriales como el glicerol. El objetivo de este trabajo fue estudiar la producción de biohidrógeno y bioetanol en un CSTR empleando tratamientos del inóculo y utilizando glicerol puro como sustrato, además, se realizó un análisis de la variación de la estructura de la comunidad microbiana con SSCP. Considerando la producción conjunta de biohidrógeno y bioetanol el mejor sistema es un pretratamiento con 4 semanas de aireación y lodo aerobio, sin embargo, una vez que se realiza un control biocinético con un inóculo pretratado y no pretratado, para ambos lodos, se alcanza una estructura de la comunidad microbiana similar pero con rendimientos de biohidrógeno y bioetanol diferentes, entonces, la estructura de la comunidad microbiana es determinada y se ve mayor influencia por el control biocinético realizado.
