Chemotaxis is a bacterial function which allows to move according to a concentration gradient. With this system bacteria can find  a better place to grow by swimming toward higher concentrations of molecules, such as nutritional molecules like sugar, amino acid, vitamins...Chemotactic-signal transducers respond to changes in the concentration of attractants and repellents in the environment, transduce a signal from the outside to the inside of the cell, and facilitate sensory adaptation through the variation of the level of methylation.

In our case, chemotaxis is used as a way to detect and approach fungi. Indeed during its growth, fungi release N-acetylglucosamine (NAG), the basic unit of chitin which composed its cell wall. Thus, the concentration of N-acetylglucosamine is getting more important around fungi.</p>
