Biodiversity of N-acyl homoserine lactonase (aiiA) gene from Bacillus subtilis.

Microorganisms rely on the benefit of using chemical signals called autoinducers (AIs) as a connection matter in term of population, this mechanism is known as quorum sensing (QS). Quorum sensing is responsible for formation of biofilm together with virulence in bacteria. The most known QS molecule is N-acyl homoserine lactones (AHLs).
