| vertical distribution and diversity of bacteria and archaea in sulfide and methane-rich cold seep sediments located at the base of the florida escarpment. | the bacterial and archaeal communities of the sediments at the base of the florida escarpment (gulf of mexico, usa) were investigated using molecular phylogenetic analysis. the total microbial community dna of each of three vertical zones (top, middle and bottom) of a sediment core was extracted and the 16s rrna genes were amplified by pcr, cloned and sequenced. shannon-weaver diversity measures of bacteria were high in all three zones. for the archaea, diversity was generally low, but increased ... | 2006 | 16465452 |
