Direct bioconversion of domestic wastewater sludge as a new substrate for bioethanol production through optimization of media

A lab-scale study was conducted to produce bioethanol using wastewater sludge as substrate by the yeast Saccharomyces cerevisiae. Direct bioconversion process was applied through media optimization for bioethanol production. The statistical optimization was carried out with four different media comp...
