This contribution reviews the mass transfer aspects of biotechnological processes for gas
treatment, with an emphasis on the underlying principles and technical feasible methods for …

Biological processes are considered to be the most cost-effective technology for the off-gas
treatment of volatile organic compounds (VOC) at low concentrations. Two-phase …

Ionic liquids (ILs) constitute a new generation of solvents entirely composed of ions. ILs are
usually considered as green solvents due to their negligible vapor pressure and other …

In aerobic cell cultivation processes, dissolved oxygen is a key process parameter, and an
optimal oxygen supply has to be ensured for proper process performance. To achieve …

A calculation procedure to determine the influence of the silicone volume fraction on the
physical absorption of VOCs in water/silicone oil mixtures is presented (ηsilicone oil …

The robustness of a conventional biofilter and an air diffusion bioreactor (ADB) was
comparatively evaluated in laboratory-scale plants treating a mixture of H2S, butanone …

Two-phase partitioning bioreactors (TPPBs) in environmental biotechnology are based on
the addition of a non-aqueous phase (NAP) into a biological process in order to overcome …

Biotrickling filters (BTFs) devoted to air pollution control often present mass transfer
limitations for hydrophobic volatile organic compounds (VOCs). Under such limiting …

Neural stem/progenitor cells (NSPCs) are able to differentiate into the primary cell types
(neurons, oligodendrocytes and astrocytes) of the adult nervous system. This attractive …

The deodorization performance of a biofilter and an activated sludge diffusion (AS) system
was comparatively evaluated in terms of removal efficiency (RE) and process stability at …
