Symbiosis can be defined as "an interaction (positive, negative, or neutral) in which two species exist in intimate physical association for most or all of their lifetimes and are physiologically dependent on each other" [1].

* Does your model allow some kind of coexistence between inhibiting and non-inhibiting bacteria? | * Does your model allow some kind of coexistence between inhibiting and non-inhibiting bacteria? | ||
