Abstract EN
The present study examined the impact of transferrin on Bacillus thuringiensis biofilms.
Three commercial strains, an environmental strain (33679), the type strain (10792), and an isolate from a diseased insect (700872), were cultured in iron restricted minimal medium.
All strains produced biofilm when grown in vinyl plates at 30°C.
B.
thuringiensis 33679 had a biofilm biomass more than twice the concentration exhibited by the other strains.
The addition of transferrin resulted in slightly increased growth yields for 2 of the 3 strains tested, including 33679.
In contrast, the addition of 50 μg/mL of transferrin resulted in an 80% decrease in biofilm levels for strain 33679.
When the growth temperature was increased to 37°C, the addition of 50 μg/mL of transferrin increased culture turbidity for only strain 33679.
Biofilm levels were again decreased in strain 33679 at 37°C.
Growth of B.
thuringiensis cultures in polystyrene resulted in a decrease in overall growth yields at 30°C, with biofilm levels significantly decreased for 33679 in the presence of transferrin.
These findings demonstrate that transferrin impacts biofilm formation in select strains of B.
thuringiensis.
Identification of these differences in biofilm regulation may be beneficial in elucidating potential virulence mechanisms among the differing strains.
