> Upon addition of a simple Cd2+ salt and the sulfur amino acid cysteine, the non-photosynthetic Moorella thermoacetica self-photosensitizes through the synthesis of light absorbing CdS nanoparticles. This hybrid organism, M. thermoacetica-CdS, produces acetic acid from CO2, water, and light at quantum efficiencies above 80%. One problem is that cadmium is toxic, highly toxic, so the removal of it before refining any fuel will have to follow strict rules. And wikipedia will have to be updated :) > Although cadmium has no known biological function in higher organisms (...) (https://en.wikipedia.org/wiki/Cadmium https://en.wikipedia.org/wiki/Cadmium)
