dc.description.abstract | Batch test was performed to evaluate the activity of methane producing bacteria (MPB) and acetate producing bacteria(APB) according to change of sulfate and sulfide concentrations. MPB activity in the 100 and 150㎎S/ℓ was inhibited by 15 and 50%, respectively, while it was stopped at over 200㎎/ℓ. This indicated that the inhibition of sulfide concentration on methane producing bacteria increased as sulfide concentration increase. Different species of anaerobic microorganisms degrading organics showed different characteristics of acclimation and inhibition depending on the sulfide concentration. APB and MPB were much affected at the sulfide concentration over 100㎎/ℓ, resulting in accumulation of acetate in the reactor. This clearly showed that APB were more persistent than MPB to sulfide toxicity. Sulfate concentration less than 2000㎎/ℓ showed no inhibition to MPB in the anaerobic treatment of organics. Moreover, higher methane production was observed with sulfate concentration of 100㎎/ℓ in the batch than in the control, suggesting that small amount of sulfate was necessary for MPB. | - |
