Kinetic parameters
Sulfate-reducing bacteria
Desulfovibriopiger Vib-7
Desulfomicrobium sp. Rod-9
V0 (µmol × min-1 × mg-1 protein)
6.16 ± 0.63
1.39 ± 0.14***
Pmax (µmol × mg-1 protein)
20.48 ± 2.51
6.74 ± 0.68***
τ (min)
3.33 ± 0.34
4.82 ± 0.49
Comment: V0 is initial (instantaneous) reaction velocity; Pmax is maximum amount (plateau) of the product of reaction; is the reaction time (half saturation period). Statistical significance of the values M ± m, n = 5; ***P<0.001, compared to the D. piger Vib-7 strain.
