In the original article, we neglected to include the funder Undergraduate “SRT Plan” project, (Guida SRT (2021) No. 271), Undergraduate “SRT Plan” project, (Guida SRT (2021) No. 271) to Tingjiang, Wang.

There was also a mistake in Table 1 as published. Errors in the formatting and data. The corrected Table appears below.

Nitrogen balances of ammonium, nitrite and nitrate removal by strain EM-A1.

Substances Initial N (mg/L) Final N (mg/L) Intracellular-N (mg/L) N lose (%)
NH4 +-N NH2OH-N NO2 −N NO3 −-N Organic-N
NH4 +-N 54.88 ± 0.47 0.72 ± 0.06 5.47 ± 0.59 0 1.29 ± 0.61 23.54 ± 0.15 13.59 ± 0.6 29.34 ± 0.18
NO2 −N 57.95 ± 0.58 4.38 ± 0.4 0 5.45 ± 0.23 4.67 ± 0.28 19.72 ± 1.02 16.24 ± 0.18 23.72 ± 0.88

Values represent mean ± S.D., of triplicates (n = 3). Final organic-N = final soluble TN − (final NH4 +-N) − (final NO3 −-N) − (final NO2 −-N) − (final NH2OH). Intracellular-N = (final TN − final soluble TN). % N removal = [(initial TN) − (final NH4 +-N) − (final NO3 −-N) − (final NO2 −-N) − (final organic-N) − (final intracellular-N) − (final NH2OH)]/initial TN × 100%.

In the published article, the rotation speed in part of “Abstract” and “Conclusion” should have been updated to 150 rpm.

The authors apologize 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.
