Agarose stabilization of fragile biofilms for quantitative structure analysis.
Agarose was used to stabilize fragile biofilms cultivated in parallel plate flow cells prior to imaging by confocal laser scanning microscopy. An essential element to the success of the procedure was the application of a ceramic heat pad to the flow cell to maintain agarose fluidity until the biofilm was enveloped. Quantitative digital image analysis demonstrated the effectiveness of this technique for generating reproducible measurements of a three-dimensional biofilm structure. The described method will also benefit researchers who transport their flow cell-cultivated biofilms to a core facility for imaging.
