With random mutagenesis and relatively simple engineering, PHB and related polyhydroxyalkanoate polymers have been produced in R. eutropha on industrial scales [3]. (microbialcellfactories.biomedcentral.com)
Then, Ralstonia eutropha bacteria consume the hydrogen gas and pull in carbon dioxide from the air. (sciencenews.org)
With a little charge, this new catalyst can assemble itself out of a solution of regular water, cobalt and phosphate — and phosphate in water actually is good for living things like the Ralstonia eutropha bacteria that make up the back half of the bionic leaf. (scientificamerican.com)
