Abstract Degradation of methyl tert-butyl ether (MTBE)
as a sole carbon and energy source was investigated uti-
lizing an enriched bacterial consortium derived from an old
environmental MTBE spill. This enriched culture grew on
MTBE with concentration up to 500 mg/l, reducing the
MTBE in medium to undetectable concentrations in
23 days. Traces of tert-butyl alcohol were detected during
MTBE degradation. The degradation was not affected by
additional cobalt ions, whereas low concentration of glu-
cose enhanced the rate of degradation. The bacterial
community consisted of numerous bacterial genera, the
majority being members of the phylum Acidobacteria and
genus Terrimonas. The alkane 1-monooxygenase (alk)
gene was detected in this consortium. Our findings suggest
that environmental degradation of MTBE proceeds along
the previously proposed pathway. |
