Fig. 4From: Characterisation of an efficient atrazine-degrading bacterium, Arthrobacter sp. ZXY-2: an attempt to lay the foundation for potential bioaugmentation applicationsKinetic relationships between the expression of three genes and atrazine degradation. Relative transcript levels were measured by RT-qPCR, using the 16S rRNA gene as a housekeeping gene, and are shown for (a) trzN, (b) atzB, and (c) atzC. At each kinetic sampling point, a Fisher’s test was performed to compare the relative transcript levels in atrazine-treated and control samples (n = 3, p < 0.05)Back to article page
