실험 절차

Accordingly, hetero-lactic fermentation of a mixture containing hexose and pentose may be performed. Hetero-lactic fermentation is conducted while neutralizing with ammonia to produce ammonium lactate and ethanol from hexose, and to produce ammonium lactate and ammonium acetate from pentose. Ammonium lactate and ammonium acetate are esterified with ethanol (if amount of ethanol obtained by fermentation is not enough, ethanol might be further added) to yield ethyl lactate and ethyl acetate, respectively. Ammonia generated at the time of esterification is recovered. Unreacted ethanol is distilled off, and purification of ethyl lactate is conducted by distillation with removing and recovering ethyl acetate.
