Gas Chromathography as a Tool in Quorum Sensing Studies

摘要: Since cell differentiation was studied cell-to-cell signaling and regulated cycles were considered exclusive of eukaryotic organisms, prokaryotic organisms regarded as isolated cells without cooperative behaviors. It took us more than 30 years, after Nealson et al., (1970) explained bioluminescence an auto-induced mechanism bacterial groups, to assume in microbiology research that bacteria can synchronize group In consequence, it possible explain inter-cell regulates some phenotypes this phenomenon called Quorum Sensing (QS). QS is one the most revolutionary mechanisms discovered past 15 years. involves control population by communication using chemical signals a complex network genetic circuits with positive feedback regulation (for review see: Waters 2005). these respond groups detect “quorum” order regulate different phenotypes.
