title: Development of a novel biofilm continuous culture method for simultaneous assessment of architecture and gaseous metabolite production.
abstract: The way that gaseous metabolite production changes along with biofilm architecture development is poorly understood. To address this question, we developed a novel flow reactor biofilm culture method that allows for simultaneous assessment of gaseous metabolite production and architecture visualization. In this report, we establish the utility of this method using denitrification by Pseudomonas aeruginosa biofilms as a model system. Using this method, we were able to collect and analyze gaseous metabolites produced by denitrification and also visualize biofilm architecture in a nondestructive manner. Thus, we propose that this novel method is a powerful tool to investigate potential relationships between biofilm architecture and the gas-producing metabolic activity of biofilms, providing new insights into biofilm ecology.
