PROBLEM TO BE SOLVED: To efficiently produce ethanol from sugar derived from lignocellulose by the continuous culture with microorganisms having xylose assimilative properties.SOLUTION: When microorganisms having xylose assimilative properties are continuously cultured with the culture medium containing sugar derived from lignocellulose, adding the additional culture medium containing sugar derived from lignocellulose to the above culture medium is regulated based on the xylose concentration measured in the culture medium.SELECTED DRAWING: Figure 3 |
