  1. aThe determination of the MIC was performed in hMB after 72 h at 30°C. Fresh antibiotic stock solutions (10 mg/ml) were made for every experiment. Test tubes were inoculated to an OD578 of 0.05 with over night cultures of the Roseobacter strains in MB at 30°C. The results represent the mean of three independent experiments performed in duplicate. Amp, ampicillin; Carb, carbenicillin; Cm, chloramphenicol; Gm, gentamicin; Kan, kanamycin; Spec, spectinomycin; Strep, streptomycin; Tc, tetracycline
