  <dc:description>&lt;p&gt;&lt;span&gt;Methyl fluoride (CH&lt;/span&gt;&lt;sub&gt;3&lt;/sub&gt;&lt;span&gt;F) and dimethyl ether (DME) inhibited nitrification in washed-cell suspensions of&amp;nbsp;&lt;/span&gt;&lt;i&gt;Nitrosomonas europaea&lt;/i&gt;&lt;span&gt;&amp;nbsp;and in a variety of oxygenated soils and sediments. Headspace additions of CH&lt;/span&gt;&lt;sub&gt;3&lt;/sub&gt;&lt;span&gt;F (10% [vol/vol]) and DME (25% [vol/vol]) fully inhibited NO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;sup&gt;-&lt;/sup&gt;&lt;span&gt;&amp;nbsp;and N&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;O production from NH&lt;/span&gt;&lt;sub&gt;4&lt;/sub&gt;&lt;sup&gt;+&lt;/sup&gt;&lt;span&gt;&amp;nbsp;in incubations of&amp;nbsp;&lt;/span&gt;&lt;i&gt;N. europaea&lt;/i&gt;&lt;span&gt;, while lower concentrations of these gases resulted in partial inhibition. Oxidation of hydroxylamine (NH&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;OH) by&amp;nbsp;&lt;/span&gt;&lt;i&gt;N. europaea&lt;/i&gt;&lt;span&gt;&amp;nbsp;and oxidation of NO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;sup&gt;-&lt;/sup&gt;&lt;span&gt;&amp;nbsp;by a&amp;nbsp;&lt;/span&gt;&lt;i&gt;Nitrobacter&lt;/i&gt;&lt;span&gt;&amp;nbsp;sp. were unaffected by CH&lt;/span&gt;&lt;sub&gt;3&lt;/sub&gt;&lt;span&gt;F or DME. In nitrifying soils, CH&lt;/span&gt;&lt;sub&gt;3&lt;/sub&gt;&lt;span&gt;F and DME inhibited N&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;O production. In field experiments with surface flux chambers and intact cores, CH&lt;/span&gt;&lt;sub&gt;3&lt;/sub&gt;&lt;span&gt;F reduced the release of N&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;O from soils to the atmosphere by 20- to 30-fold. Inhibition by CH&lt;/span&gt;&lt;sub&gt;3&lt;/sub&gt;&lt;span&gt;F also resulted in decreased NO&lt;/span&gt;&lt;sub&gt;3&lt;/sub&gt;&lt;sup&gt;-&lt;/sup&gt;&lt;span&gt;&amp;nbsp;+ NO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;sup&gt;-&lt;/sup&gt;&lt;span&gt;&amp;nbsp;levels and increased NH&lt;/span&gt;&lt;sub&gt;4&lt;/sub&gt;&lt;sup&gt;+&lt;/sup&gt;&lt;span&gt;&amp;nbsp;levels in soils. CH&lt;/span&gt;&lt;sub&gt;3&lt;/sub&gt;&lt;span&gt;F did not affect patterns of dissimilatory nitrate reduction to ammonia in cell suspensions of a nitrate-respiring bacterium, nor did it affect N&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;O metabolism in denitrifying soils. CH&lt;/span&gt;&lt;sub&gt;3&lt;/sub&gt;&lt;span&gt;F and DME will be useful in discriminating N&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;O production via nitrification and denitrification when both processes occur and in decoupling these processes by blocking NO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;sup&gt;-&lt;/sup&gt;&lt;span&gt;&amp;nbsp;and NO&lt;/span&gt;&lt;sub&gt;3&lt;/sub&gt;&lt;sup&gt;-&lt;/sup&gt;&lt;span&gt;&amp;nbsp;production.&lt;/span&gt;&lt;/p&gt;</dc:description>
