Biofilm deposition varies by strain and material type in vitro. Staphylococcus epidermidis (A), Streptococcus agalactiae (B), Proprionibacterium (C), Kocuria spp (D), Bacillus licheniformis (E), or Mycobacterium dioxanotrophicus was incubated together in a continuous-flow stir tank bioreactor with a series of coupons of different material types for 72 h. After the incubation period, the coupons were removed and biofilm deposition was assessed through plate count assays. Negative controls, wherein media without strain inoculation was subjected to identical bioreactor conditions were performed, and consistently did not harbor growth on plate count assays. Error bars indicated standard deviation. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001.
