Scientists turn CO2 into a powerful cancer-fighting compound

A new bacteria-based technology could help combat climate change while producing a valuable antioxidant.

Researchers from Qingdao Agricultural University in China’s Shandong province have developed this technological solution.

The South China Morning Post (SCMP) reported that the technology aims to capture carbon dioxide and utilize it to produce lycopene. The compound is a powerful antioxidant found in fruits and vegetables. It gives tomatoes, watermelons, and peppers their reddish pigment. Moreover, lycopene is thought to have protective properties against various diseases, such as heart disease, certain cancers, and diabetes. It may also support bone health.

The new “synthetic biology technology” offers a more sustainable approach as compared to traditional methods. The team led by researcher Yang Jianming describes it as a low-cost, and easy-to-implement method for producing lycopene. The team harnessed the power of microorganisms to capture carbon dioxide and convert it into lycopene. This innovative process, known as carbon fixation, mimics the natural process plants use to create organic compounds.

Reportedly, the technology relies on microorganisms that serve as bioreactors. This method can produce various products (such as materials or medicines) while lowering carbon emissions. Particularly, Yang has been studying the production of lycopene using a naturally occurring bacterium called Rhodopseudomonas palustris. This bacterium can be found in various natural environments, such as marine sediments and pond water.
