The Photanol® concept
|
From Solar Energy and Carbondioxide to fuels and valuable compounds
|
|
The Photanol® concept is based on the capacity of cyanobacteria to capture sun light efficiently and to use that energy for the
reduction of the green house gas CO2 to organic compounds. By genetically introducing properties of fermentative bacteria into
these cyanobacteria, their metabolism is altered in a controlled manner such that the organic compounds are further converted to
valuable compounds such as ethanol, butanol, propanediol and many others. These product are excreted by the cells.
Thus, when exposed to sun light, the organisms serve as catalysts that convert carbon dioxide to biofuels in solution.
The only byproduct formed is oxygen and hence the Photanol® process is an absolutely clean process that consumes carbon
dioxide and is driven by solar energy. Its technology is simple and cheap.

The Photanol® concept combines the properties of photosynthetic and fermenting bacteria into
a 'photofermenting' bacterium
that uses solar energy to reduce CO2 to any of a variety of organic compounds, including alcohols.
Oxygen is the only waste product.
