1. A method for managing a batch fermentation process in a biofuel production process, comprising:

  • providing a nonlinear control model of yeast growth and fermentable sugar concentration for biofuel production in a batch fermentation process of a biofuel production process;

    receiving process information for the batch fermentation process;

    executing the nonlinear control model of yeast growth and fermentable sugar concentration using the process information as input to determine values of one or more fermentation process variables for the batch fermentation process for substantially maximizing yeast growth and achieving target fermentable sugar concentrations; and

    controlling the batch fermentation process in accordance with the determined values for the one or more fermentation process variables to substantially maximize yeast growth and achieve target fermentable sugar concentrations, wherein said substantially maximizing yeast growth and achieving target fermentable sugar concentrations substantially maximizes biofuel production in the batch fermentation process.
