DFAA will definitiely make it into the nitrogen cycle. The real question is the form that it will take. Some of the DFAA will get passed through into the main system (the most "clean" entry into the nitrogen cycle), but most of it will get assimilated for catalysis into bacterial structural components. Entry into the nitrogen cycle may be further delayed until the cellular component degrades.
Not unless there's a shear force to dislodge bits of the biomass from the surface it's growing on, although a small percentage of the denitrifiers will undergo normal detachment processes.

This
could happen ... but only if specific types of bacteria and the appropriate microclimate (low O2, for example) are present. Specifically, there would need to be some strain of SRB ("sulfur-reducing bacteria") present. Aside from the structural uses for amino acids, different strains of bacteria will do
wildly different things with an amino acid. The differences in metabolic behavior between, for example, general heterotrophs, nitrifiers, denitrifiers, SRB, IOB, and fermenters (all of which have been speculated to be in marine aquaria, or are commonly used in marine aquaculture) is significant.
