The archaebacterial communities in Antarctic bathypelagic sediments
16S ribosomal DNA clone library analysis was performed to assess archaeal diversity within three surficial sediment samples obtained from the bathypelagic zone (depth: 2165-3406 m) of the Weddell Sea, Antarctica. The nearly complete 16S rDNA gene (1440 bp) was obtained for 146 clones and 46 phylotyp...
