Provided are: a method for producing a deodorant which is derived from earthworm castings and can be used in a liquid form; and a deodorant. The deodorant production method characterized by including a mixing step of mixing earthworm castings with water and a collecting step of collecting vaporized water generated from a mixture obtained in the mixing step to obtain a liquid; and the deodorant produced by the production method. It is preferred to further mix an organic substance together with the earthworm castings and the water in the mixing step.

Provided is a facilitated COtransport membrane having an improved COpermeance and an improved CO/Hselectivity. The facilitated COtransport membrane includes a separation-functional membrane that includes a hydrophilic polymer gel membrane containing a COcarrier and a COhydration catalyst. Further preferably, the COhydration catalyst at least has catalytic activity at a temperature of 100&#xb0; C. or higher, has a melting point of 200&#xb0; C. or higher, or is soluble in water.

Provided is a simple and easy method of producing an innoxious dry earthworm powder, while suppressing inactivation of the enzymes contained in earthworms. In the method, a homogenate obtained by grinding living earthworms is freeze-dried and the dried product is heat-treated at a temperature of 110&#xb0; C. or higher but lower than 130&#xb0; C. Preferably, the method according to the present invention comprises further a process for preparation of the living earthworms, which precedes the grinding step, comprising the steps of: standing the living earthworms under light for 10 to 50 hours; removing the dirt formed on the skin thereof, bringing the earthworms into contact with an organic acid for 30 seconds or less; diluting the acid with addition of water to adjust the pH of the aqueous acidic solution to a pH in the range of 2 to 5; standing the earthworm mixture under the pH condition for 3 to 180 minutes; and then washing the earthworms with water.
