For tissue samples, lung or liver tissue was homogenized in a 15 mL Eppendorf tube using a disposable microtube pestle (Eppendorf, San Diego, CA) and scalpel, and RNA extraction was then performed using TRIzol LS (Invitrogen, Carlsbad, CA), followed by isopropanol precipitation and two washes in 70 % ethanol.

In other words, for every kilowatt - hour of electricity used the microbes could scrub 130 grams of CO2 out of 230,000 liters of air to make 60 grams of isopropanol fuel. (scientificamerican.com)
The nanowires collect sunlight, much like the light - absorbing layer on a solar panel, and the bacteria use the energy from that sunlight to carry out chemical reactions that turn carbon dioxide into a liquid fuel such as isopropanol. (sciencenews.org)
