Qteros (formerly SunEthanol) is an emerging biofuels company focused on microbe technology. The scientists and energy experts are unlocking the sugars from trees, plants, and other plentiful nonfood biomass. With the Q Microbe, they will transform eco-friendly biomass into cellulosic ethanol more efficiently than with any other technology available today. Because the process starts with a naturally occurring, renewable microbe, it is simple, clean, and very close to being carbon-neutral. Once they apply the technology on a commercial scale, locally produced transportation fuel will be cheaper, cleaner, and sustainable as long as the sun keeps shining.
