Anaerobic Oxidation of Hydrogen Sulfide in Batch Bioreactor Using Micro Organism Isolated from Ramsar Hot Spring
Removal of hydrogen sulfide from mixed gas was successfully carried out in a batch reactor. The isolated microorganism from Ramsar hot spring was cultured and adapted in an environment with hydrogen sulfide. At 35℃, maximum cell dry weight was 0.43 g/l. For the hydrogen sulfide removal, effect of te...

| description | Removal of hydrogen sulfide from mixed gas was successfully carried out in a batch reactor. The isolated microorganism from Ramsar hot spring was cultured and adapted in an environment with hydrogen sulfide. At 35℃, maximum cell dry weight was 0.43 g/l. For the hydrogen sulfide removal, effect of temperature in the range of 25 to 45℃ was investigated. The experimental results showed that the removal efficiency significantly increased with an increase in temperature from 25 to 35℃, then; a slightly decrease in media temperature at 45℃ appeared. Maximum and minimum removal efficiencies of hydrogen sulfide were 72 and 25%, respectively. At 35℃, based on first order biochemical kinetic; the rate of substrate utilization was 0.06 h-1. |
