Denitrification Characteristics of the Low-Temperature Tolerant Denitrification Strain <i>Achromobacter spiritinus</i> HS2 and Its Application.

From Figure 4 D–F, it was evident that the optimal C/N ratio for strain HS2 was 20–30, with over 95% removal rates of total nitrogen and ammonium nitrogen within 72 h, and all experimental groups showed an increasing trend in total nitrogen and ammonium nitrogen removal rates between 24–72 h.
