Supporting information as cited in the literature has been provided
which demonstrates that the biodegradation of cyanuric acid is dependent
on the specific microorganisms present.
Normally, cyanuric acid degrades very slowly under aerobic conditions
since the majority of aerobic microorganisms do not possess the genes to
produce the specific enzymes required to degrade cyanuric acid. As
a result, cyanuric acid shows minimal biodegradation in standard
screening tests conducted at atmospheric oxygen levels and with no
However, cyanuric acid can be degraded much more rapidly if: 1) specific
fungal or bacterial strains are present which contain the genes/enzymes
required, 2) the microorganisms have been acclimated to cyanuric acid,
and 3) organic nutrients are present for the microorganisms. Furthermore,
since bacteria degrade cyanuric acid in order to obtain ammonia for use
in synthesis of biomass, the biodegradation of cyanuric acid is normally
more pronounced if the ambient conditions are nitrogen-limited, but will
be less likely to occur if more readily degraded sources of
ammonia-nitrogen are present.
