Corrigendum to “ Kinetics and microbial ecology of batch sulfidogenic bioreactors for co-treatment of municipal wastewater and acid mine drainage” [J. Hazard. Mater. (2016) 10.1016/j.jhazmat.2015.11.041] (S0304389415302417) (10.1016/j.jhazmat.2015.11.041))

The authors regret that their paper titled “Kinetics and microbial ecology of batch sulfidogenic bioreactors for co-treatment of municipal wastewater and acid mine drainage” contains an error: Recently we have found that there was a mistake in calculation of Km value. The paper currently states Km = 4.3 mg/L, but the Km value should have been 6220 mg/L. The changes that need to be made include correcting the Km value in the abstract and Table 2, and a revision to the statement in a paragraph: Original: “The maximum COD oxidation rate (Vmax) and Michaelis–Menten constant (Km) were estimated as 0.33 mg/L min and 4.3 mg/L, respectively (Fig. 1a). The Km value was comparable to a similar study using mining granular sludge as a source of SRB [43] and lower than other studies using pure SRB cultures [4–46] (Table 2). The relatively low value of Km obtained in this study suggested that Vmax can be reasonably achieved in the co-treatment process given the typical COD values in MWW and anticipated mixing with AMD” We propose to change this paragraph to “The maximum COD oxidation rate (Vmax) and Michaelis–Menten constant (Km) were estimated as 0.33 mg/L min and 6220 mg/L, respectively (Fig. 1a). The Km value was much higher than studies using mining granular sludge as a source of SRB [43] and other studies using pure SRB cultures [4–46] (Table 2).”
