Controlling biofilm dynamics to unlock the future of biofilm-based biocatalysis

Biofilms have emerged as promising biocatalysts due to their distinct structural and functional advantages. Since biofilm dynamics shape biofilm architecture and catalytic performance, engineering strategies to control these dynamics are key to improving biofilm-based catalysis. In this review, we outline the fundamental features and catalytic benefits of biofilms, with a focus on biofilm dynamics. We highlight recent advances in regulatory strategies, from the manipulation of biofilm-associated genes to the design of synthetic circuits based on signaling networks that govern biofilm development. We further discuss current challenges, including limited regulatory efficiency, restricted applicability beyond model organisms, and the need for biofilm functional enhancement. Collectively, these insights position the control of biofilm dynamics as a frontier for advancing next-generation biofilm-based biocatalysis.
