摘要:
The present invention relates a method for reactivating or regenerating the methane oxidizability of a methane-utilizing bacteria which have partly or wholly lost its methane oxidizability by culturing said methane-utilizing bacteria in a specified condition, and further relates to a method for continuous production of oxides by bringing a methane-utilizing bacteria in contact with alkanes, alkenes or cyclic compounds.
