- Municipal wastewater treatment
- Removal of hydrogen sulfide and nitrate from waste streams
- Generation of biofuel or biobased chemicals as by-product of wastewater treatment
- Combines wastewater remediation with biofuel / high value chemical production
- Offers carbon sequestration (CO2 fixation)
- No organic electron donors are required and less sludge is produced
Berkeley Lab seeks a partner(s) to fund the development and commercialization of a sustainable wastewater treatment process that uses a genetically engineered bacterium to simultaneously remove hydrogen sulfide, carbon dioxide, and nitrate from waste streams, such as municipal wastewater, and produce fatty acid derived biofuels or bio-based chemicals.
The JBEI technology, developed by researcher Harry Beller,
- oxidizes hydrogen sulfide, a corrosive, toxic, and malodorous compound, to sulfate,
- reduces nitrate and / or nitrite to nitrogen gas,
- converts CO2, a greenhouse gas, to biofuels or biobased chemicals.
No added exogenous electron donors / organic carbon sources are required. The bacterium uses the metabolic energy derived from sulfide oxidation and the carbon derived from CO2 to generate desired products.
DEVELOPMENT STAGE: Early stage – collaborative research opportunity.
STATUS: Patent pending. Available for collaborative research or license.
