PLASMIDS ORIGINATING IN AMMONIA OXIDIZING BACTERIA AND USE OF THE SAME

摘要

A plasmid characterized by having the base sequence represented by SEQ ID NO:1; a plasmid characterized by having the base sequence represented by SEQ ID NO:2; a plasmid characterized by having at least a part of the base sequences represented by SEQ ID NO:1 and SEQ ID NO:2 and containing a selective marker gene, each plasmid being usable as a transformation vector, etc. for effecting gene manipulation in ammonia oxidizing bacteria; and transformants, etc. characterized by being prepared by introducing these plasmids into hosts.
