Methane has what scientists would describe as super radiation-trapping abilities. However, they use different starting materials, like acetate. Discover world-changing science. The abundance of methane-oxidizing bacteria was significantly decreased by elevated [CO2] and LN in both soil layers at the rice MR stage and by ET in the upper soil layer. “We’re really interested in the enzyme nitrogenase because it does a phenomenally difficult reaction,” she said. "This method involves a reaction of nanoparticles called cerium oxide with carbon dioxide in presence of ruthenium catalyst with an electric field," explains Sekine.

On the other hand, the new engineered nitrogenase in R. palustris converts carbon dioxide into methane on its own in a single step, simplifying the process. “The methanogens require other microbes to provide them with other electron donors,” he said. ScienceDaily. Scientists have engineered a bacterium that can take carbon dioxide from the air and turn it into fuel in a single enzymatic step. In this newly-developed method reported in Chemistry Letters, carbon dioxide can be converted into methane more efficiently and quickly in the 100 degrees Celsius range. But this modified enzyme was tediously produced in test tubes at small scales, which isn’t good enough for a process that might one day produce industrial quantities of biofuels. Researchers here now have a picture of a key molecule that lets microbes produce carbon dioxide and methane, the two greenhouse gases associated with global warming. Especially, methane can be used not only as fuel but also as a hydrogen carrier, transporting town gas to existing infrastructure. These engineered bacteria could guide scientists toward better carbon-neutral biofuels. With this novel method, methane could be produced from carbon dioxide collected from the atmosphere, possibly enabling an unlimited amount of methane production by recycling carbon dioxide from the atmosphere released from factories into valuable energy resources.

Lessner studies a class of bacteria called methanogens that naturally produce methane. Daniel Lessner, an associate professor in the department of biological sciences at the University of Arkansas, Fayetteville, who was not involved in the study, said the findings chalk out a clearer pathway to produce methane, the major component of natural gas, from living organisms.
