A method for providing sugar to a microbial culture comprising the steps of:
- a. feeding sugar to a microbial culture growing in fermentation medium at an initial rate;
- b. measuring ethanol concentration in off-gas from the fermentation medium;
- c. when the ethanol concentration in the off-gas increases, decreasing the sugar feed rate;
- and
- d. when the ethanol concentration in the off-gas decreases, increasing the sugar feed rate.
