Abstract
Developing renewable energetic matrices became strategic at a current scenario in which environmental sustainability appeared as a great global concern. In this context, in Brazil, the biorefinery emerges as an industry centered in the production of biofuels, bioethanol and biodiesel, in parallel with the production of other biomolecules with high added-value. Focusing the biofuels synthesis by the biochemical route, the in-house production of useful enzymes for obtaining bioethanol and biodiesel may assure self-supply. For that, solid-state fermentation (SSF) shows as feasible alternative for these enzymes production as well as for production of other molecules interesting to biorefineries as inputs or final products, employing as raw materials sub or co-products of the biorefinery itself. On the above, it is proposed this regular research project focused on building and operation of a packed-bed bioreactor for pseudo-continuous production of enzymes and other biomolecules by SSF. It will contemplate experimental tests and modeling and simulation in a modular packed-bed bioreactor here named pseudo-continuous, that will be operated as a plug flow reactor. In this reactor, modules will be moved ascendingly like clusters that will compose the body of the packed-bed. After an initial transient period, once the desired bed height is achieved, steady-state operation will be reached. The instrumentation of the equipment aiming monitoring and control is also contemplated. At the end of the project, it is expected to have a SSF bioreactor feasible, patentable and industrially applicable, once it is novel in experimental aspect. (AU)
