The novelty of this study lies in the integration of fermentation in a magnetically stabilized fluidized bed bioreactor with S. cerevisiae supported on calcium alginate with magnetic particles and using levoglucosan, a pyrolytic sugar from sugarcane bagasse, as a substrate for bioethanol production. Sugarcane bagasse was pretreated with acetic acid to remove alkali/alkaline earth metals (AAEMs) aiming to intensify levoglucosan...

The reduction of nitric oxide (NO) emissions to atmosphere has been recently addressed using biological technologies. However, NO removal through bioprocesses is quite challenging due to the low solubility of NO in water. Therefore, the abatement of NO emissions might be improved by adding a chelating agent or a mass transfer vector (MTV) to increase the solubility of this pollutant into the aqueous phase where the bioprocess...
