Biodegradation of biphenyl in a solid–liquid two-phase partitioning bioreactor
Biphenyl was successfully degraded by Burkholderia xenovorans LB400, initially described as Pseudomonas sp. LB400, in a solid–liquid wo-phase partitioning bioreactor (TPPB). Solid–liquid TPPBs are comprised of an aqueous, cell containing phase, and a solid polymeric phase hat partitions toxic and/or poorly soluble substrates (in this case biphenyl) based on maintaining a thermodynamic equilibri...
متن کاملEnhanced hexane biodegradation in a two phase partitioning bioreactor: Overcoming pollutant transport limitations
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 ...
متن کاملA novel solid-liquid two-phase partitioning bioreactor for the enhanced bioproduction of 3-methylcatechol.
The bioproduction of 3-methylcatechol from toluene via Pseudomonas putida MC2 was performed in a solid-liquid two-phase partitioning bioreactor with the intent of increasing yield and productivity over a single-phase system. The solid phase consisted of HYTREL, a thermoplastic polymer that was shown to possess superior affinity for the inhibitory 3-methylcatechol compared to other candidate pol...
متن کامل2,4-Dichlorophenol removal in a solid-liquid two phase partitioning bioreactor (TPPB): kinetics of absorption, desorption and biodegradation.
The applicability of a sequencing batch two phase partitioning bioreactor (TPPB) to the biodegradation of a highly toxic compound, 2,4-dichlorophenol (DCP) (EC(50)=2.3-40 mgL(-1)) was investigated. A kinetic study of the individual process steps (DCP absorption into the polymer, desorption and biodegradation) was performed and, based on favourable absorption/desorption characteristics (DCP diff...
متن کاملSolvent selection for enhanced bioproduction of 3-methylcatechol in a two-phase partitioning bioreactor.
The biotransformation of toluene to 3-methycatechol (3MC) via Pseudomonas putida MC2 was used as a model system for the development of a biphasic process offering enhanced overall volumetric productivity. Three factors were investigated for the identification of an appropriate organic solvent and they included solvent toxicity, bioavailability of the solvent as well as solvent affinity for 3MC....
