Cellular adaptation and the importance of the purine biosynthesis pathway during biofilm formation in Gram-positive pathogens

M. Gelinas, L. Museau, A. Milot, P. B. Beauregard

This study identifies purine biosynthesis as a key pathway upregulated during biofilm formation in Gram-positive bacteria, suggesting it as a potential anti-biofilm target.

Surfactin production is not essential for pellicle and root-associated biofilm development of Bacillus subtilis

M. Therien, H. T. Kiesewalter, E. Auria, V. Charron-Lamoureux, M. Wibowo, G. Maroti, A. T. Kovacs, P. B. Beauregard

This study shows surfactin production is not essential for pellicle or root-associated biofilm formation in Bacillus subtilis, but reduces colony expansion.
