Effects of soil and water content on methyl bromide oxidation by the ammonia-oxidizing bacterium Nitrosomonas europaea.
Little information exists on the potential of NH(3)-oxidizing bacteria to cooxidize halogenated hydrocarbons in soil. A study was conducted to examine the cooxidation of methyl bromide (MeBr) by an NH(3)-oxidizing bacterium, Nitrosomonas europaea, under soil conditions. Soil and its water content modified the availability of NH(4)(+) and MeBr and influenced the relative rates of substrate (NH(3)) 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.
