China to produce single-cell protein from carbon monoxide

Thursday, November 4, 2021

The Feed Research Institute of the Chinese Academy of Agricultural Sciences and Beijing Shoulang Biotechnology Co. found a way to produce single-cell protein from Clostridium autoethanogenum with carbon monoxide from steel plants that could be used in animal feeds, local news said. 

The team developed a gas fermentation process that produces Clostridium autoethanogenum single-cell protein with a profile close to fishmeal and far better than soy meal, paving the way for a reduction in soy-imported proteins in the country. Researchers from the Feed Research Institute tested this protein in several fish species and found it suitable for fish feeds. The team aims to reduce soy-import dependence and achieve carbon neutrality.

After six years of research, Beijing Shoulang Biotechnology achieved a three-year stable pilot production and completed a 10,000-ton protein production facility this year. The company plans to increase production by up to 30,000 tons. The company recently received China's first product certificate for feed ingredients from Clostridium autoethanogenum protein.
