In the original article, there was an error in Figure 4 as published. The absolute abundances of sul1, sul2, intI1 and 16S rRNA gene were calculated incorrectly.
Figure 4.
Absolute abundance of sul1, sul2, intI1 and 16S rRNA gene determined by quantitative real-time PCR. Number of replicates (n) = 15.
The corrected Figure 4 and its caption “Figure 4. Absolute abundance of sul1, sul2, intI1 and 16S rRNA gene determined by quantitative real time PCR. Number of replicates (n) = 15.” appears below.
In the original article, there was an error in the results section. The absolute abundances of sul1, sul2, intI1 and 16S rRNA gene were calculated incorrectly.
A correction has been made to Results, ARG abundance, Paragraph 1. This sentence previously stated:
“The absolute copy numbers of the 16S rRNA gene per 100 mL did not exceed 2 × 105 in river water and 5 × 105 in the WWTP effluent.”
The corrected sentence appears below:
“The absolute copy numbers of the 16S rRNA gene per 100 mL did not exceed 9 × 106 in river water and 2.5 × 106 in the WWTP effluent.”
The author apologizes for these errors and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
