Article Abstract:

Research has been conducted on the NH (sub)3 -oxidizing bacteria. The cooxidation of methyl bromide by NH (sub)3 -oxidizing bacterium Nitrosomonas europaea under soil conditions has been examined.

Global transcriptional response of nitrosomonas europaea to chloroform and chloromethane

Article Abstract:

The protein expression and specific mRNA levels at 1, 2, and 3 h after the addition of chloform (CF) is analysed to choose the time point to examine the whole-genome transcriptional stress responses of N. europaea. Transformation of CF leads to an irreversible loss of ammonia monooxygenase activity.

Effects of soil on ammonia, ethylene, chloroethane, and 1,1,1-trichloroethane oxidation by Nitrosomonas europaea

Article Abstract:

Research was conducted to examine the effects of soil on ammonia, ethylene, chloroethane, and 1,1,1-trichloroethane (TC) oxidation by Nitrosomonas europaea. The cosubstrates are well-characterized inhibitors of ammonia monooxygenase (AMO) activity in N europaea. TC is oxidized by AMO and yielded products that inactivate ammonia oxidation while ethylene and chloroethane are oxidized by AMO with little effect on the cell. Results indicate that the addition of soil to cultures had a pronounced inhibitory effect on the oxidation of NH3.
