Liquid state bioconversion of domestic wastewater sludge for bioethanol production

The production of bioethanol was conduct-ed by utilizing domestic wastewater sludge as major substrate using the yeast, Saccharomyces cerevisiae in liquid state bioconversion method (submerged fermenta-tion). The optimum media and process conditions ob-tained from previous studies by using central c...
