A closed-system bioreactor consisting of 0.5 L of a growing culture of a previously described bacterium, strain IMB-1, removed MeBr (&amp;gt;110 μmol L&lt;sup&gt;-1&lt;/sup&gt;) from recirculating air. Strain IMB-1 grew slowly to high cell densities in the bioreactor using MeBr as its sole carbon and energy source. Bacterial oxidation of MeBr produced CO&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;and hydrobromic acid (HBr), which required continuous neutralization with NaOH for the system to operate effectively. Strain IMB-1 was capable of sustained oxidation of large amounts of MeBr (170 mmol in 46 d). In an open-system bioreactor (10-L fermenter), strain IMB-1 oxidized a continuous supply of MeBr (220 μmol L&lt;sup&gt;-1&lt;/sup&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;in air). Growth was continuous, and 0.5 mol of MeBr was removed from the air supply in 14 d. The specific rate of MeBr oxidation was 7 × 10&lt;sup&gt;-16&lt;/sup&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;mol cell&lt;sup&gt;-1&lt;/sup&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;h&lt;sup&gt;-1&lt;/sup&gt;. Bioreactors such as these can therefore be used to remove large quantities of contaminant MeBr, which opens the possibility of biodegradation as a practical means for its disposal.&lt;/p&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div class="article_content"&gt;&lt;div class="container container_scaled-down"&gt;&lt;div class="row"&gt;&lt;div class="col-xs-12"&gt;&lt;div class="article_content-table"&gt;&lt;div class="article_content-row"&gt;&lt;div class="article_content-left hlFld-FullText ui-resizable"&gt;&lt;div id="" class="NLM_sec NLM_sec_level_1"&gt;&lt;div class="article_content-header"&gt;&lt;div class="article_content-header-row"&gt;&lt;div class="article_content-title"&gt;&lt;br data-mce-bogus="1"&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</dc:description>
