Liquid state bioconversion of domestic wastewater sludge for bioethanol production

The production of bioethanol was conducted by utilizing domestic wastewater sludge as major substrate using the yeast, Saccharomyces cerevisiae in liquid state bioconversion method (submerged fermentation). The optimum media and process conditions obtained from previous studies by using central comp...
