<p>An enzyme referred to as carbon monoxidase and referred to here inafter as CMase is present in animal tissue such as the plasma or cells of red blood and in various bacterial and plants, including algae and fungi. The enzyme is effective for the conversion of carbon monoxide in a gas stream. Where the conversion is the step of oxidizing CO to CO2, the enzyme can be used for detection of CO. The procedure lends itself to quantitative determination of CO in a gas stream. The production of CMase can be accelerated by growing bacterial cultures or plants in an atmosphere containing an increased concentration simultaneously is also beneficial to the process. A filter medium including CMase can substantially decrease the concentration of carbon monoxide in a gas stream, the gas stream of particular interest being tobacco smoke. Combining the CMase in a filter with compounds which bind CO reversibly presents advantages.</p> |
