BELGIUM - Nutriad has demonstrated the use of quorum sensing as a tool in the development of new feed additives for livestock and aquaculture applications. quorum sensing (QS) is a form of bacterial communication that is critical to bacterial virulence. Following Nutriad’s introduction of quorum sensing Inhibition as a tool to fight bacterial diseases in aquaculture at the TARS meeting in 2012, this year Dr Goossens presented more basic insight in Nutriad’s EMS strategy including the different The chemical messengers released from the coating interfere with the cell-to-cell communication between bacteria called quorum sensing, and also can induce bacteria to break up an infectious biofilm, making the bacteria more susceptible to conventional It was recently discovered that bacteria actually talk to one another, in a process called quorum sensing. This cross-talk is one of the factors that regulate biofilm formation. When certain molecules detect a sufficiently high cell density, they activate One colony of resistant bacteria (dark spot) is able to digest a fluorescent nutrient to produce a light-blue halo. Regular microbes (light spots) that are close by can grab enough of the nutrient to survive. Traditional antibiotics wipe out large swaths No matter how many times it's demonstrated, it's still hard to envision bacteria as social, communicating creatures. But by using a signaling system called "quorum sensing," these single-celled organisms radically alter their behavior to suit their population. .

Bacteria use a signaling system called quorum sensing to alter behavior within a population. The quorum-sensing messages are carried in small molecules that the bacteria release and whose concentration bacteria can measure. Once the population of bacteria One of the great mysteries of modern science has been how when bacteria congregate in small numbers, they are relatively innocuous. However, when the amount of bacteria grows, it is as if a switch goes on and they go from being a clump of innocuous New tools and techniques are allowing researchers to not only understand why bacteria communicate but also to manipulate these communication streams to improve antibiotics and to develop clean energy technologies. Margaret A. Woodbury investigates. This article is going to throw another idea into the pot about computer based algorithms with an idea borrowed from Microbiology titled "Quorum Sensing". Nature has been in the business of survival and evolution for billions of years, so it should come as .
