Unc., Uncultured; nd, 16S rRNA sequence not detected; Treatments: ciprofloxacin (Cipr), Sulfomethoxazole (Sulf), trimethoprim (Trim); Controls: synthetic seawater (SS), acetone (Ac), dimethylsulfoxid (DMSO). Percentages are rounded to the nearest whole number and the corresponding number of clones per library is given in brackets.
