  <dc:description>&lt;p&gt;&lt;span&gt;Methyl fluoride (MF) and dimethyl ether (DME) were effective inhibitors of aerobic methanotrophy in a variety of soils. MF and DME blocked consumption of CH&lt;/span&gt;&lt;sub&gt;4&lt;/sub&gt;&lt;span&gt;&amp;nbsp;as well as the oxidation of&amp;nbsp;&lt;/span&gt;&lt;sup&gt;14&lt;/sup&gt;&lt;span&gt;CH&lt;/span&gt;&lt;sub&gt;4&lt;/sub&gt;&lt;span&gt;&amp;nbsp;to&amp;nbsp;&lt;/span&gt;&lt;sup&gt;14&lt;/sup&gt;&lt;span&gt;CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;, but neither MF nor DME affected the oxidation of [&lt;/span&gt;&lt;sup&gt;14&lt;/sup&gt;&lt;span&gt;C]methanol or [&lt;/span&gt;&lt;sup&gt;14&lt;/sup&gt;&lt;span&gt;C]formate to&amp;nbsp;&lt;/span&gt;&lt;sup&gt;14&lt;/sup&gt;&lt;span&gt;CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;. Cooxidation of ethane and propane by methane-oxidizing soils was also inhibited by MF. Nitrification (ammonia oxidation) in soils was inhibited by both MF and DME. Production of N&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;O via nitrification was inhibited by MF; however, MF did not affect N&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;O production associated with denitrification. Methanogenesis was partially inhibited by MF but not by DME. Methane oxidation was ∼100-fold more sensitive to MF than was methanogenesis, indicating that an optimum concentration could be employed to selectively block methanotrophy. MF inhibited methane oxidation by cell suspensions of&amp;nbsp;&lt;/span&gt;&lt;i&gt;Methylococcus capsulatus&lt;/i&gt;&lt;span&gt;; however, DME was a much less effective inhibitor.&lt;/span&gt;&lt;/p&gt;</dc:description>
