Notes.

Cultures were inoculated at 0.05 to 0.1 OD₆₀₀, and samples were immediately taken to measure ${\mathrm{NO}}_3^{-}$ (Initial). After prescribed times (estimated from prior culture tests), the whole cultures were taken (Final) to collect the biomass and to measure ${\mathrm{NO}}_3^{-}$ and OD₆₀₀. Values are from triplicate cultures with standard deviation under parentheses.

< <AN > >

anoxic conditions

< <O > >

oxic conditions, no ${\mathrm{NO}}_3^{-}$

< <ON > >

oxic conditions with ${\mathrm{NO}}_3^{-}$
