Deactivation of TCE and ammonium degradation
It has been shown previously that TCE cometabolism can be
toxic/inhibitory towards ammonium oxidizing bacteria (Ely et al.,
1997; Powell et al., 2011). In the result reported here, the microbial
deactivation was not observed at low TCE concentrations; at 29
and 46lgL

TCE, the meank1-TCE(Table 1) and TCE initial degra-dation rate (Table 1S in SM) stayed relatively stable through
7 weeks (cycles AMT 1-7). However, keeping the ammonium con-centration constant and increasing the TCE concentration to
