Transferrin Impacts Bacillus thuringiensis Biofilm Levels

Figure 4

(a) B. thuringiensis strains form biofilms in polystyrene plates. CTM was inoculated to an OD₆₀₀ of 0.02 and incubated in CTM for 24 hours at 30°C. Culture turbidity was measured in a plate reader at OD₆₂₀. Samples are presented as the average. Asterisks indicate a statistically significant () change as compared to the no transferrin samples. (b) Transferrin decreases biofilm formation in certain B. thuringiensis strains in polystyrene plates. CTM was inoculated to an OD₆₀₀ of 0.02 and incubated for 24 hours at 30°C. Samples were analyzed for biofilm biomass as described. Biofilm levels indicate a change in biomass relative to the baseline. Asterisks indicate a statistically significant () change as compared to the no transferrin samples.
