Abstract
A system and method for managing an ethanologen for use in biorefinery is disclosed. The method for propagating ethanologen for use in the production of a fermentation product from biomass omprises the steps of providing a medium for propagation of ethanologen and supplying a first cell mass of ethanologen to the medium. A first cell mass of ethanologen is propagated into a larger second cell mass of ethanologen. The system for propagating ethanologen for use in the production of a fermentation product from biomass comprises a first stage comprising a first vessel configured to maintain a medium comprising ethanologen and a second stage comprising a second vessel configured to maintain a medium supplied from the first stage.
