| characterizing microbial diversity in production water from an alaskan mesothermic petroleum reservoir with two independent molecular methods. | the phylogenetic diversity of bacteria and archaea within a biodegraded, mesothermic petroleum reservoir in the schrader bluff formation of alaska was examined by two culture-independent methods based on fosmid and small-subunit rrna gene pcr clone libraries. despite the exclusion of certain groups by each method, there was overall no significant qualitative difference in the diversity of phylotypes recovered by the two methods. the resident bacteria belonged to at least 14 phylum-level lineages ... | 2009 | 18771500 |
