Currently, most of the world’s sulfur is produced as a by-product of the treatment of gas streams that come from the mining of fossil fuels. These gas streams contain dihydrogen sulfide (H2S), which is recovered and transformed into sulfur using both energy and chemically intensive processes. As the world transitions to using more sustainable forms of energy, sulfur production will decrease and may no longer be available for use in industries such as agriculture. The biodesulfurization technology utilizes sulfide oxidizing bacteria (SOB) that convert H2S gas to elemental sulfur under ambient conditions making it more sustainable than physiochemical processes. SOB remove sulfide (HS-) in anaerobic conditions and reduce oxygen in sulfide-free condition . This ability is called the shuttling capacity of the SOB, and theunderlying mechanisms are not understood. Therefore, a multi-scale approach is needed to understand this ability.
This offer will focus on running and maintaining a continuous lab-scale reactor. It also includes continuous sampling and monitoring of the reactor. The goal is to monitor the shuttling-capacity during operation and provide real-time information on
the process performance and potentially implement new process schemes.
• Maintain a continuous bioreactor system
• Perform sampling and analysis of water samples using different methods
