Figure 3. Denitrifying activities and dynamics of H. nitrativorans strain NL23 and M. nitratireducenticrescens in the biofilm cultures.

Figure 3

(A, B) Quantification of M. nitratireducenticrescens strains JAM1/GP59 (narG1), M. nitratireducenticrescens strain JAM1 (tagH), M. nitratireducenticrescens strain GP59 (nirK) and Hyphomicrobium nitrativorans strain NL23 (napA) by qPCR in the corresponding biofilm cultures. Results from triplicate cultures. OB: Original biofilm. Significance of the qPCR levels (log10 transformed) of the respective genes between the biofilm cultures were determined by one-way ANOVA with Tukey’s Multiple Comparison Test. Rates with the same letter (within the bar) are not significantly different.
