CH391L/S12/Bacterial Odor Engineering
Bacterial communities are capable of producing a wide variety of odor molecules. At its most basic, an odorant is simply a volatile chemical compound that triggers an olfactory response. These compounds fall into many categories, and a few examples will be discussed here. Although bacteria don't have an olfactory system in the same sense as higher organisms, there is evidence that bacterial communities can communicate via volatile airborne compounds and that they may be an important bacterial defense sensor.
