Biofilm formation in Vibrio cholera is triggered by ________ cell densities and repressed by ________ cell densities.

Question

Quizplus · Accepted Answer

Biofilm formation in Vibrio cholera is triggered by low cell densities and repressed by high cell densities. At low cell densities, the signaling molecule, known as autoinducer-2 (AI-2), is produced and accumulates, which leads to the expression of genes required for biofilm formation. At high cell densities, the AI-2 concentration is diluted, which represses biofilm formation.
