- High cell density reactor for the production of Lactobacillus plantarumPublication . Barreto, M. T. O.; Melo, E. P.; Moreira, J. L.; Carrondo, M. J. T.The production of a flocculent strain of Lactobacillus plantarum was performed in a high cell density reactor: a fluidized bed reactor (FBR) with a settler and an external cell recirculation. Two variables were assessed, the recirculation rate (R) and the dilution rate (D). The effect of the latter is much more important than the effect of the former in ensuring a quick start up in the flocculation process. The cell volumetric productivities obtained with this system increase directly with dilution rate and recirculation rate. The values of cell volumetric productivities obtained are considerably higher than those obtained in continuous stirred tank reactors (CSTR) and much higher than in batch reactors.
- Starter culture production in fluidized bed reactor with a flocculent strain ofL. plantarumPublication . Barreto, M. T. O.; Melo, E. P.; Carrondo, M. J. T.A lactic starter culture of a flocculentLactobacillus plantarum was produced in a fluidized bed reactor with higher cell volumetric productivities than in a continuous stirred tank reactor. The fluidized bed reactor was operated at optimised parameters obtained in batch reactor performed with and without pH control.
