Quantification of bacteria in biofilms grown for 64.5 h in SAL, mFUM4, and iHS growth medium. Bacteria were quantified by visual microscopic counting. Each box represents N=9 independent biofilms from three independent experiments. The boxes represent the inter quartile range of the data points, the bar indicates the median. The whiskers cover the data points within the 1.5x inter quartile range. Dots are outliers within 1.5 and 3 box lengths outside the interquartile range, and colored stars are extremes that are more than 3 boxlengths outside the interquartile range. * indicate significant differences with p≤0.05 between a pair of boxes, as indicated by the brackets.
