Figure 2. Growth (a), carbon (b), nitrate and nitrite concentrations (c) in batch denitrification tests of Paracoccus pantotrophus P16 grown in a synthetic medium containing 4.5 µM Fe3+, 700 mg NO3--N/l and various concentrations of carbons. ▲ = 800 mg C/l ethanol, ● = 800 mg C/l glucose and ■ = 1600 mg C/l glucose. Acetate (◊) was detected when ethanol was utilized. Levels of nitrite were represented as ∆. Standard deviations of growth, glucose concentrations did not exceed 5% while for nitrate and nitrite concentrations did not exceed 10% of their corresponding values.
