| Abstract: | The biotechnology of flask batch and fed-batch culture to produce yeast from cornhusk hydrolysate was studied and the fed -batch process in 10L bioreactor was conducted. Suitable concentration of materials in the medium were 2% saccharide and 7% bran extract. The yeast concentration in flask batch culture, flask fed-batch and 10L bioreactor reached 10.9g/L, 21.6g/L and 20.7g/L respectively. |
