Two-phase partitioning bioreactors: a new technology platform for destroying xenobiotics

Toxic organic compounds (xenobiotics) pose serious environmental and health risks worldwide. Biological treatment of these materials is severely constrained by their toxic and inhibitory nature and great care is required with respect to the rate at which they are provided to cells. The use of a second, distinct, organic phase in a bioreactor has been shown to provide a virtually foolproof means of feeding substrate to cells because this process concept relies only on thermodynamic equilibrium and the cellsʹown rate of metabolism. This technology can be applied to stockpiled xenobiotics as well as contamination of air, water and soil environments.
