In this paper, we report a simultaneous realization of both efficient ethanol production and saving medium nutrient (corn steep liquor [CSL]) during bioethanol fermentation of overliming-treated hydrolysate of waste house wood (WHW) using ethanologenic Escherichia coli KO11. In cultivation using WHW hydrolysate supplemented with 4% (v/v) CSL and 0.2 g-dry cell weight (DCW)/l E. coli KO11 cells, the overall ethanol yield reached 84% of the theoretical value at 61 h. When we conducted the… CONTINUE READING
