A method for producing activated carbon for electrodes of electric double layer capacitors is disclosed which comprises an activation step wherein activated carbon is obtained by mixing an alkali metal hydroxide with a carbon raw material for the activated carbon and heating the mixture in an inert gas atmosphere, a deactivation removal step wherein the alkali metal in the activated carbon is deactivated and removed, and a heat treatment step wherein the activated carbon having gone through the deactivation removal step is heated in an inert gas atmosphere at a temperature higher than 400° C. but not higher than the heating temperature in the activation step. Also disclosed are activated carbon produced by such a method, activated carbon for electrodes of electric double layer capacitors wherein the alkali metal content is less than 100 mass ppm, activated carbon for electrodes of electric double layer capacitors having specific impedance characteristics, and activated carbon for electrodes of electric double layer capacitors having a specific amount of surface functional groups and a specific amount of surface carboxyl groups. In an electric double layer capacitor comprising a pair of electrodes and an electrolyte solution, at least one of the electrodes contains such an activated carbon.

This invention provides a method for producing cantlhaxanithin, which is inexpensive, stably provided, and highly safe. This method comprises steps of: inducing mutation in astaxanthin-producing microorganisms in which the nucleotide sequence of DNA corresponding to its 16S ribosomal RNA is substantially homologous to the nucleotide sequence as shown in SEQ ID NO: 1; obtaining canthaxanthin-producing microorganisms by selecting a mutant having a higher ratio of canthaxanthin produced (% by mass) relative to the total amount of carotenoid produced than that of a parent strain; and recovering canthaxanthin or a carotenoid mixture comprising canthaxanthin from the culture product of the canthaxanthin-producing microorganisms.
