Abstract

Research and development in advanced technology for fermentation processes is currently foccused in obtaining high density cell cultures. From the main techniques currently employed, flocculation is the one with the lowest operating costs (less mixing and recirculation energy). This is a relevant incentive for the study of its suitability for the production of medium or low added value products. This work deals with the production of ethanol from lactose, using a flocculating strain of Kluyveromyces marxianus in a flocculation bioreactor with cell recycle.
