Graphic representation of colony-forming units per milliliter (CFU/mL) from the bacterial germ count after 24 h of cultivating the bacteria on different structured, flat and a neutral control surface of glass. No statistically significant differences were found between the different surfaces for any of the bacteria. However, for strain 19/827 and 19/941 the boxplot graphic indicates that the bacterial colonies increase slightly with the increasing size of the cylinders
