The use of an organic solvent can allow to increase the mass transfer, and thereby biodegradation, of hydrophobic gaseous pollutants. The biodegradation of hexane by a Pseudomonas aeruginosa strain was thus optimized in a two phase partitioning bioreactor (TPPB). Silicone oil was first selected among various organic solvents based on its biocompatibility and resistance to P. aeruginosa and its ...
Formaldehyde (FA) is a very toxic pollutant. FA in indoor air has a negative effect on human health and should be removed by ventilation or by conversion to non-toxic products. The formaldehyde dehydrogenase (FdDH), a NADand glutathione-dependent enzyme from recombinant methylotrophic yeast Hansenula polymorpha, was tested for its ability to oxidize airborne FA. A continuous fluidized bed biore...
