FIG 2.
Net production of N2O (white bars) and NH4+ (hatched bars) over a 5-day incubation period at 21°C in S. loihica strain PV-4 cultures amended with 5.0 mM lactate and different NO2−:NO3− ratios to achieve 1.0 mM total N-oxyanion concentration. Each bar represents the averages from triplicate samples, with the error bars representing their standard deviations.
