A BBC report on the August 2017 American Chemical Society meeting states ‘Cyborg’ bacteria deliver green fuel source from sunlight. To summarise, some bacteria deal with heavy metals such as cadmium by converting it to cadmium sulphide semiconductor crystals on their surfaces. These bacteria are then able to convert carbon dioxide + water + light into acetic acid with high efficiency. This is really interesting and perhaps important stuff.
