Little information exists on the potential of NH3 -oxidizing bacteria to cooxidize halogenated hydrocarbons in soil. A study was conducted to examine the cooxidation of methyl bromide (MeBr) by an NH3 -oxidizing bacterium,Nitrosomonas europaea , under soil conditions. Soil and its water content modified the availability of NH4 + and MeBr and influenced the relative rates of substrate (NH3 ) and cosubstrate (MeBr) oxidations. These observations highlight the complexity associated with characterizing soil cooxidative activities when soil and water interact to differentially affect substrate and cosubstrate availabilities.
