The aim of this research line is the design and optimization of bioreactors for the removal of pollutants from effluents gases, such as  air treatment (odour removal) and biogas desulfurization. It is worth noting the results obtained in the removal of ammonia, hydrogen sulphide (H₂S) and reduced sulphur compounds (dimethyl disulphide, methyl mercaptan, etc.).

The more significant results are:
