a
Planktonic cultures were grown by continuous culture. Biofilm-derived culture was grown in the GPT device. Biofilms were grown in the CDFF.
b
Fluoride-containing solutions (i.e., all media except deionized water and basal medium) were adjusted to 250 mg of fluoride liter−1. Values are means of viable counts from triplicate runs of each device.
