The one-carbon gas protein (C1GP) is produced through the fermentation of certain unique microorganisms by utilizing the substrates from one carbon-related industrial exhaust gases, such as methane, methanol, carbon monoxide, carbon dioxide, through research from the CAAS Institute of Feed Research and the CAS Tianjin Institute of Industrial Biotechnology. A gas fermentation for the production of protein from CO was developed using Clostridium ethanolicum. The anaerobic microorganism is usually studied for its capacity to transform CO into ethanol, similar to C. ljungdahlii. The researchers found that if ammonia was added fermentation could be directed towards the rapid production of cell mass in high yield, with a protein content of 80% and an amino acid composition similar to fish meal.
