a

The substrate was added directly to the culture medium (5 μl) at a final concentration of ∼200 mg liter−1.

b

The substrate was added after dissolution into HMN (5 μl/0.5 ml of HMN).

c

The values are means based on the values obtained for two test flasks; the extent of degradation was calculated as described in Materials and Methods.

d

The values are means based on the values obtained for two test flasks; the extent of mineralization was calculated as described in Materials and Methods and with respect to the substrate degraded.

e

The results are the average value of two independent measurements. ND, not determined; NT, not tested.

f

TBA was produced stoichiometrically, confirming the ether degradation measurement.
