Figure 6

Phage titers in the effluent of long term biofilms (the same biofilms assayed in Figure 5). The horizontal axis gives the number of days of phage treatment. Although titers one day after phage addition show some scatter, all treatments are clustered near 10⁷/mL by day 3. Red: T7dsp (T7trx+dsp _10B), black: T7+, blue: an equal mixture of T7+ and T7dsp, and gray: an equal mixture of T7v and T7dsp. Error bars of ± 1 std. err. are shown. Logs are to base 10.
