Carbon recycling technology. This technology uses bacteria to convert waste gas (pollution) to fuels and chemicals. Carbon gas streams are common byproducts of established processes. LanzaTech utilizes these gas streams to produce fuels such as ethanol and chemicals such as 2,3-butanediol at high selectivities and yields. LanzaTech's microbes can also consume H2-free CO-only gas streams due to a biological water-gas shift reaction with CO2 and CO catalyzed by carbon monoxide dehydrogenase. Conventional chemical pathways require the presence of hydrogen in the gas mixture, which limits many industrial processes that do not produce hydrogen as a byproduct. The greenhouse gas emissions from this fuel production method are 50-70% lower than fossil fuel emissions.
