Are readily culturable bacteria in coastal North Sea waters suppressed by selective grazing mortality?

abstract：:Shuttle vectors that replicate stably and express selectable phenotypes in both Thermococcus kodakaraensis and Escherichia coli have been constructed. Plasmid pTN1 from Thermococcus nautilis was ligated to the commercial vector pCR2.1-TOPO, and selectable markers were added so that T. kodakaraensis transformants could...
