Chemical brewers

Microbes are principally used by industry to turn larger organic compounds into smaller, more useful ones – fermenting corn sugars to produce ethanol, for instance. More desirable, though, is direct conversion of carbon dioxide into organic compounds. But current methods that use blue-green algae are not attractive.

Now US researchers have engineered a heat-loving microbe to produce a bulk chemical from carbon dioxide and hydrogen. Their results may provide a viable industrial alternative to blue-green algae, which have a much lower efficiency for such chemical transformations.
