Respiration of methyl tert-butyl ether (MTBE) degrading microorganisms

Original language description

Fuel oxygenates added to petrols in last 15 years are water soluble ethers such as methyl-tert-butyl ether (MTBE). In the Czech Republic MTBE has been produced in amount of about 92 000 tons per year in recent years. It is probable that the risk of environmental pollution may be rather higher in the CR than in other countries which are not self-sufficient with the oxygenates. Several bacterial strains and consortia capable to utilize MTBE were isolated from fuel-contaminated sites. The screening was based on monitoring of selected microorganisms in the presence of MTBE. The ability of microorganisms to degrade MTBE as the sole carbon source or by cometabolism with other substrates was monitored by gas chromatography with FID detection. Enzymes responsible for MTBE utilization have not yet been defined. We tested our isolated bacterial consortia for endogenous respiration and for for the ability of the strains to aerobically metabolize MTBE by monitoring their respiration with this and

Dýchání bakteriálního konsorcia Nem v přítomnosti MTBE

Czech description

Již 15 let se přidávájí do pohonných hmot kyslíkatá aditiva v podobě ve vodě dobře rozpustných etherů jako je např. terc-butyl(methyl)ether (MTBE). V České republice je ročně vyprodukováno okolo 92 000 tun MTBE. MTBE představuje pro životní prostředí velkou zátěž, jelikož je téměř rekalcitrantní. Tato práce je zaměřena na studium respirace bakterálnho konsorcia Nem dlouhodobě kultivovaného v přítomnosti MTBE pomocí přístroje OROBOROS Oxygraph-2k, na jeho charakterizaci a na sledování jeho utilizace MTBEpomocí GC/FID.
