Using Micro Organism Isolated from Ramsar Hot Spring

Abstract: 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°C, maximum cell dry weight was 0.43 g/l. For the hydrogen sulfide removal, effect of temperature in the range of 25 to 45°C was investigated. The experimental results showed that the removal efficiency significantly increased with an increase in temperature from 25 to 35°C, then; a slightly decrease in media temperature at 45°C appeared. Maximum and minimum removal efficiencies of hydrogen sulfide were 72 and 1 oxidizing bacteria INTRODUCTION variety of biological desulphurization processes for Presence of hydrogen sulfide in natural gas is operates at ambient temperature and atmospheric pressure considered as one of the most noxious gases. Removal of may eliminate high costs for heat and pressure generation the hydrogen sulfide from sour natural gas is required for in a variety of chemical processes [10-14].
