Continuous culture for the production of ethanol from wood hydrolysate was carried out in an internal membrane-filtration bioreactor. The medium sterilized at a relatively low temperature 60 °C with intention reducing formation inhibitory compounds during sterilization. maximum concentration and productivity obtained this study were 76.9 g/L 16.9 g/L-h, respectively, which much higher than those (57.2–67 0.3–1.0 g/L-h) batch cultures using media °C. also found to be that (6.7 continuous cell retention 121 These results show bioreactor combination low-temperature sterilization could very effective hydrolysate.
