RIKEN scientists have discovered a new microorganism that may help us understand the origins of life on Earth and how to improve microbial factories. The microorganism, an archaeon called Met12, was found in the deep-water-fed springs of northern California. It converts carbon dioxide into other chemicals, using a previously unknown metabolic pathway that may mimic the earliest forms of energy metabolism on Earth. This process could be used to produce biofuels and chemicals. The microbe thrives in an unusual environment with high levels of calcium, hydrogen, and methane gas, but lacking other essential elements. The discovery has practical implications for improving the efficiency of genetically engineered microbes used to produce biofuels and chemicals. It could also aid in carbon sequestration, a crucial strategy for slowing down climate change. The team is now searching for other extremophile organisms in unique environments, such as hot springs and underwater volcanoes. The discovery of Met12 and other such microorganisms could provide clues to the origins of life on Earth and elsewhere in the universe. The team’s research could lead to the development of new technologies and a better understanding of the diversity of microbial life.
