Transferrin Impacts Bacillus thuringiensis Biofilm Levels

Figure 3

(a) B. thuringiensis strains grow in vinyl plates at 37°C. CTM was inoculated to an OD₆₀₀ of 0.02 and incubated for 24 hours at 37°C. Culture turbidity was measured in a plate reader at OD₆₂₀. Samples are presented as the average. (b) Transferrin decreases biofilm formation in certain B. thuringiensis strains in vinyl plates at 37°C. CTM was inoculated to an OD₆₀₀ of 0.02 and incubated for 24 hours at 37°C. Samples were analyzed for biofilm biomass as described. Biofilm biomass was detected by the addition of alcohol decolorizer. Biofilm levels indicate a change in biomass relative to the baseline. Samples are presented as the average.
